04 CDTI ZT VIN/drowned ECU/key question
Hi all, I only have the one key, RCL has never worked since I've had the car, osf door latch is faulty.
I'm concerned at only having one way into the car so need the RCL working. The closest people I've found to do it are 25/30 miles away and closest who can cut a blade another 10 or so on from them. Long story short the guy asked if I knew the history of the car and whether it had had a drowned ECU, ie if it's had the required components from another car we will have problems with codes stored by BMW, so before I made the trip I thought I would see if the ECU VIN matches the car. Option 1 on the self test function gives me a matching 5 digits to the last of my VIN plate. Does this mean I'm good to go and the cluster reads the VIN straight from the ECU or is the VIN written to the cluster so wouldn't change if a rescue kit had been fitted? |
To save guessing pop the main ECU out and you should find a sticker on it with the VIN, hopefully it should match the car.
Guess the closest people are up in Newton Abbot, but don't know if they can supply a complete working key including the transponder chip, ask them. They can probably supply you with a working door latch too. Regards |
Info (VIN, mileage etc) isn't only stored in the ECU, its also stored in other electrical control systems such as the LSM (light switch module). Unless a T4 was involved in matching a replacement ECU to the car it would throw up problems, error would show where the mileage is displayed for one.

Not too sure of the ERR appearing as long as the LSM and the IPK match.
The Newton Abbot garage have a T4 and should be able to help diagnosing the RCL problem - never heard they can do a transponder chip though, which is why I suggested he asks, agree if he wants a complete spare key and Newton Abbot can't help then Chris is nearest. But if he can be without the car for a few days I believe he can post his EWS to one of the experts and get a new transponder that way - it's a fair distance up to Portsmouth. Regards |

Newton Abbot can indeed help. :)
I guess as I used to do all this sort of thing with Fiat/Alfa Romeo I was being nosey/trying to cover all bases before I waste a day. Just wanted to do all I could before I venture up there as I have the kids for half term and didn't want make a wasted trip with two bored, moaning teenagers in tow! :drool4: Whoever it was I spoke to knew exactly what was needed and assures me it is all doable other than cutting a blade. I will have a look at the ECU this afternoon and report back. |

order one of these,
