LCR Ecu???

[richybigman]

Hi,
Has anyone ever had to replace thier ECU in the LCR? Reason i ask if i'm having a problem with boost spikes and fluctuation of boost. I've had the car in a local garage for 3 days on their rolling road and they have tried everything they can but still can't stop the boost problem. Could the ECU realistacly cause the problem i'm having?

Any help appreciated

is the garage a VW specialist like JKM?

If not - it might be worth talking to them.... it could (and more than likely) will be something like the N75 valve which controls the boost

It was JKM i took it to. LOL! They checked and replaced everything but we can't figure out what's causing the problem.

I had a problem with a hairline crack in the hose connecting the N75 to the actuator - this led to erratic boost control.

The crack was diffficult to see - I had take the hose off to check it properly.

Which hose is that? Where abouts should i look? I don't know where the N75 valve is.

It`s installed in the turbo inlet hose - just after the maf - almost at the bulkhead on the passenger`s side - a small black `cube` shaped device, with an electrical connector on top.

I think the garage ckecked all the hoses but it doesn't hurt to have another look. Cheers mate.

My car now has the same problem as you mate, you probrally remember me pulling 265hp at JKM in December, now I can only pull 240 ish, they said my car runs on the RR just like yours, also they said that your car had this problem about 3-4 months after you had Revo?, if this is right my car is the same.
