У Вас была система «Помощь при начале движения» на авто с АКПП? Очень интересно, расскажите пожалуйста.

Вы будете смеяться, но таки да. Она есть на всех автоматах. Только эта система «ручная», точнее «ножная». Вы отпускаете педаль тормоза левой ногой, а правой нажимаете газ при нужном положении селектора автомата. Понимаете теперь принцип работы? Если нет, давайте объясню дальше. Весь фокус в том, что на автомате мы можем это делать одновременно, а на МКПП нет. Проходит некоторый промежуток времени, нужный нам на переброс ноги с тормоза на газ, и вот как раз в этот момент машина откатывается. Система работает так. Условия: машина стоит, но не на ручнике, датчик наклона сигналит о том, что наклон более 5 градусов, двигатель работает и главное, нажата педаль ТОРМОЗА. Кстати если барахлит концевик педали тормоза или по нему в мозгах есть ошибка, система не сработает. Сцепление вообще не участвует, потому что момент «схватывания» сцепления почти никогда не соответствует положению концевика педали сцепления. А значит, сигнал от него будет вводить в заблуждение систему. Играют основную роль сигналы от педалей тормоза и газа. А от датчика АБС берется только сигнал скорости, равной нолю, а не то что Вы написали. При активации системы она просто дает задержку по времени, нужную водителю для переноса ноги с тормоза на газ. Это 1-1,5 секунды. То есть АБС в течение этого времени не открывает перепускные клапана тормозов, не позволяя колесным механизмам растормозиться. Клапана постепенно открываются по истечению этого времени, или же если система видит нажатие газа. Но именно постепенно, а не рывком, давая возможность водителю плавно тронуться.

I just thought I’d post an update to this ongoing issue, for the benefit of others in future and in case any experts see this and can offer further help.

The original problem from March of intermittent engine cutting out and seemingly random engine management codes is still occurring. I’ve been keeping diary of the issues to help with troubleshooting and here’s a summary of that diary. I first noticed the van cutting out in March — full details in my first post, but due to lockdown and a backlog at the Peugeot dealership the van wasn’t looked at by the dealer until 9th July. However, prior to this I called out an auto-electrician to try to expediate a solution. He used a professional looking «Snap On» scanner to read the diagnostic codes. He showed me an error the scanner screen which said «ecu internal fault». He quoted me £1500 for a new ECU and Body Control Module. I declined as the vehicle was under warranty and while I was happy to pay his call out charge in the hope of a quick fix, incurring a £1500 cost for something that should be a warranty issue wasn’t an option.

So the van went in to Perrys on 9th July. I got a call from them later in the day asking to keep the van a bit longer to investigate. I was happy to do this as I didn’t need the van for a few days. However, I chased after a week and no work had been done, I was told it would be taken for a test drive that day to log the diagnostics to try and capture the errors when they occurred. I chased a few days later and still nothing had been done. Again, I was told the work would be done urgently, so I waited a few more days (into the third week now) and chased again. The test drive still hadn’t been done so I complained. The test-drive was completed that day. The test drive covered c40 miles and did not encounter any issues. The ecu received a software update and the van was also checked for a recall item. No other work was done. I then took the van for a 40 mile test drive to see for myself if the cutting out returned. It didn’t so I was hopeful that after covering 80 miles in the last two days that the ECU reset and software update had resolved the issue.

It hadn’t. I got the van back from the dealers at the end of July. I drove the van only on a few short journeys during August as I was still working on the conversion so it wasn’t ready for any long journeys. On the 4th Sept the engine cut out after nine miles. I pulled over and the engine restarted first time. The engine management light came on. I was less than 100 metres from home fortunately, so I drove home, parked up and restarted the engine a few minutes later and the engine management light was off.

I booked the van back in to Perrys. Due to their backlog the earliest date available was 25th Sept.

I drove a few short journeys in the next three days (at quiet times on roads I know well where I know I could safely pull over) to see if the problem recurred. It did on 9th September, in similar circumstances to 4th, close to home after driving a round trip of c 9 miles. This time the engine didn’t cut out but warning for Hill Holder unavailable and ESC unavailable were displayed.

I then did some basic checks as follows and bought an obd scanner to use the next time faults occurred. I removed the earth strap between the gearbox and chassis after testing the resistance between the two ends of the cable using a multi-meter. There was more resistance measured that I would have expected across a short section of braided steel but that might have been because I could get a clean connection with the multimeter probes, so I removed the cable and gave the ends a clean with a wire brush as well as the bolts and the mounting points to the gearbox and chassis to ensure a good clean connection. The resistance was tested on refitting the strap and was, as expected zero. I did this as a preventive measure to rule out any earthing issues that might be affecting the electrical signals to/from the ECU. (I have bought a spare earth strap and might fit this as well if needed). I checked the battery and the voltage was a bit low at 12.2v which was probably not unusual as the van hadn’t been used much and hadn’t had any long runs where it would get recharged, so I charged the battery overnight. Voltage after recharging was 12.5v. Voltage under light load (ignition on/engine not running),dropped to around 12v. This seem ok. I also checked the alternator output and the voltage across the battery terminals when the van was running and this was a consistent 14.1v, so I don’t think the battery/alternator are any cause for concern.

13th Sept Engine stuttered but didn’t cut out completely and warning for hill holder and ESC not available were displayed after driving van for 18 miles. Engine management light came on and stayed on. Plugged in the odb scanner to read the trouble codes. (Scanner used is in the glove box). The following errors were stored in obd:

U0140 — Lost Communication with Body Control Module,

P0500 — Vehicle Speed Sensor A,

U0315 — Software incompatibility with Anti-lock Brake System Control Module,

U0121 — Lost Communication with Anti-Lock Brake System (ABS) Control Module,

U1064 — Manufacturer control.

14th Sept, Started van in the morning but not driven. «Check engine» and MIL still displaying. Checked battery voltage which was good at 12.4v. Removed the near side headlight and had a thorough visual inspection of the wiring harness in this area. There seems to be more moisture in this area then I would expect and some of the wiring strapping was damp to touch. There was also significant wet/damp around the cable below what looks like the ABS pump. I dried the cable harness in this area as best as I could with a cloth and sprayed some WD40 to displace any remaining moisture. I also covered the area with a plastic sheet to prevent water splashing in this area.

15th Sept, Started van in the morning but not driven. «Check engine» and MIL no longer displaying.

25th Sept, Van was due to go in to Perrys today, but as my daughter has recently tested positive for Covid-19 I am self-isolating so have had to cancel the appointment. Waiting for the problem to reoccur before booking in again.

30th Sept Warranty was due to expire so as a precaution I’ve taken out an extra year’s extended warranty.

October, van only used for short runs e.g. regular 6-8 mile round trips. No long journeys undertaken. Longest single journey before 28 October is was 15 miles. No issues with van until 28th.

I was getting slightly confident that the measures I took in September might have improved things and took the van on a longer run. First leg of the journey 25 miles was uneventful. Things were looking good. However on the return home after 24 miles, the engine cut out completely and multiple warnings were display on the dashboard, including a parking assist warning, an ABS warning, a temperature warning, but these didn’t get saved so I’m not sure of the exact codes. The van wouldn’t turn over initially when I tried to restart it, but after waiting couple of minutes and trying again it restarted. I carefully drove the last 1/2 mile home and parked on the drive. I turned the engine off and tried to restart it but it wouldn’t. I plugged the scanner in and it couldn’t receive a signal from the vehicle (first time that has happened). Also with the ignition on the reversing warning beep was sounding even though the van was not in reverse gear. This morning I tried to start the van and it started first time (it has never failed to start from cold). I plugged the scanner in and it found two codes: U0140 — Lost Communication with Body Control Module,U0073 Control Module Communication Bus Off.

I’ve rebooked the van into Perry’s but the soonest appointment is 24th November due to Covid backog! Seven months after the problem first occurred I’m no nearer a resolution and the due to the nature of the problem the van is unsafe to drive.

I have to say I don’t have a great deal of confidence in the dealers but don’t feel I have much alternative at this stage. If I don’t get a resolution when it goes in to them in November I’m not sure what my options are. Any further suggestions would be appreciated. I’d also consider taking the van anywhere in the UK to a reputable Peugeot expert if I can find one, or if someone can recommend one.
