Anyone had problems after a remap?

[tigger73]

...so who is at fault then?

Is the user who drove the car before it was properly lubricated, a failure in the lubrication system or bad oil?

Did anyone check the oil that was put in at last service was correct for the engine.

Good to hear that the tuner has done the right thing in getting it all independently assessed and agree that the tune can't be held responsible for that type of failure.

Be interesting to get the VW report....

Hi,

Just so everyone is clear about the situation, (because there is some pretty slanderous stuff in this thread), here is our version of events following the remap which we carried out on the Tiguan...

Initially we were shocked to find out that number 4 big end bearing had failed on Naresh's car, so we started our own investigations. The exact remapping file used was sent to two independent remapping companies (who actually make their own software), who said that the remap was acceptable and could not have caused damage.

We then employed a highly regarded Independent Auto Engineer (who has done this sort of thing most of his life) to go and inspect the engine at VW, ascertain why the engine failed and produce a report stating his findings.

His conclusions state that number 4 big end bearing suffered from a momentary lack of lubrication, and the bearing shell spun inside the con rod. Because number 4 bearing is the furthest away from the oil pump, it is likely that the engine had been starved of oil OR driven before the oil pressure had reached an adequate level. All of the 3 other end bearings were inspected and were perfect.

We have been remapping cars for almost 8 years now and we have never known an engine failure directly related to a remap.

Obviously, we feel bad for Naresh having to pay for a new engine, but we cannot be held responsible given the circumstances.

Finally, we are certainly not "cowboys"... we have applied the same parameters to many 2.0 TDI CR's before the Tiguan and have done since without issue.

Kind regards,
Mike.

Good on you for jumping on here and explaining the situation, also good job on getting your own independent assessment done but seems that over there as it is here, VAG don't take that as proof that something could have been their fault. Did you also happen to consult with Naresh as to the results of your findings? This is relevant because the dealership and seemingly VW uk have taken the immediate stance of the tune being at fault. If this was mentioned whatsoever by any VW representative thn you will have grounds (both naresh and also your business potentially for defamation) to take to court.

I just hope your civil tribunals over there aren't as clogged up as ours because I people contesting speeding fines

I did say I was generalising (see the bit in parenthesis in my original post)

However, overall, I'll always prefer a person (independent or not) who has a manufacturer with some size and standing behind them suppling the goods

Regarding the topic if this thread though, heated posts are understandable but perhaps not warranted based on info supplied - we've all seen that before
