E92 Ecu Failure?

Hi all, hope I've got this in the right section...

My 6 year old E92 (320i SE) has had endless problems with the engine, the starters, ignition coils you name it.

I've been on forums before and seen that this engine does have it's issues but so far they've all been solved relatively inexpensively since the warranty ran out.

Now my garage has told me that the ECU has 'failed' and they have no way of testing it to see if repairable. I'm not taking it to BMW as I don't have a money tree and my garage is well known and the head mecahnic is a good mate, so they won't b*llsh*t me.

Anyway, the ECU has been sent to Bosch in Germany and come back saying they are unable to test it. Solution now is to buy a new one but at over £1200 incl everything I'd rather have one last crack at seeing if it can get repaired. Does anyone know a decent ECU tester or have had similar problems?

Should ECU's fail after only six years? I'm guessing I have no comeback on BMW but this car is a real lemon, anyone else sharing my frustration? Shame because I love it (and my last coupe to bits).

Hello mate,

VERY sorry to hear of these problems. On a car so new! very unusual being a BMW n all. Kinda why i play safe and stick to cars older than me! :rolleyes:

I don't know of any ECU specialist repairers but tuning companies are always messing about with them so maybe they can connect it to the ol' laptop and see what's really going on maybe?

Also.. if it is knackered. EBAY!! Search on ebay for people breaking existing E92s. Should be quite a few as people do tend to wrap um round lamp posts..

As above... Has to be identical part numbers or it'll have trouble communicating with the other modules ;)

Thanks for the responses and apparently you can't do second hand, as Jack correctly says...

Cost me £1400... :-(

Not what SpannerMan is saying. You can use second hand but needs to be removed from an identical car mate

Needs to come from a car that has the same electrical options fitted I think, like sunroof etc otherwise it won't be compatible then the only thing to sort out would be an immobaliser reset.

Either way - very difficult to source! Thanks again for the help.

Another quick question - do you know what differential ratio it is for a 2007 320i SE E92? That's my new problem...

But not got mine listed! :wacko:

Don't make it easy for you do they!

Thanks Jack anyway, the people I'm talking to say the correct one for the chassis is 3.46, they have one in apparently good condition, £450. Seems best bet unless anyone knows better?

      M240i wheel advice

      Hi, just looking for some advice, my 2019 240i has these wheels as standard, they are a bit tarnished and i was considering refurbing them There is a set from a 240 M sport on ebay, they look mint but have black gloss inserts. I don't see them as an option in my brochure, but the sizes look identical. Would these be a good purchase or should I go back to refurb of mine? Thankyou Dave

      Instrument cluster suddenly died

      A few weeks ago my instrument panel on my 2004 e61 stopped working properly, the only thing that worked were the two small screens in the middle so I opened it to check what was wrong and then there was a path in the circuit board that had blown on the way in/out from the processor, so I ordered a new one. It arrived in the post today so I installed The new one and everything worked fine the first drive, but on the second drive it was broken and only the two small screens in the middle worked. Has anyone experienced this before or know what could be the cause? When the car is moving either speed, rpm, fuel efficiency etc does not work and the two small screens are much brighter than they should be

      Mini One 2004 Buying Advice

      Well I ended up buying it. Bodywork needs a good pollish, and I got the front discs and pads changed at the weekend. Got the rears to do overchristmas but at least it stops now and is driveable. Fortunately it is the first cheap car I have bought where every single nut and bolt came off without much effort. Callipers slid off, pistons were nice and free, and I didn't have to take the big hammer to the discs to release them from the rust. I love people who believe in a little copperslip!!! Done a few wee trips in it and the other half has used it on a couple of longer motorway trips so far. Couple of knocks and bangs to be investigated, one of them I am sure is the exhaust. I don't like the look of the way those springs are set up on the front suspension though!!! Looks like if one of them goes then your tyre is getting mangled too!!! Thrust bearing on clutch sounds a little noisy and there appears to be some noise similar to the tappits on a mk3 escort. I'll have a good poke about on google and see what I can dig out, plus get myself the Haynes manual. No noise from timing chain which is good. All in all it's a tidy wee car for not a lot of money

      E87 Whine on acceleration

      Great advice gents, got a similar type of noise, literally started today, definite cyclic in nature so linked to the belt and pulleys and will try the WD40 first to see if I can isolate the cause of it before moving on.
