Hi All,
Was out in the car last night, foot down and not very much happened. Still accelerated (still goes to redline so confirming it doesn't 'seem' like a limp mode really where i understand it would keep revs low?) , but not like usual (not holding me into the seat if that makes sense). Car off and on again ;) No joy. No warnings etc.
The car is remapped and uses a Bluefin Map, so I removed this, test drive and car seems standard, been so long that i drove without the map, its hard to tell of any difference with standard but its definitely still slower without remap than with remap and current problem combined but i can tell its not right. Remap installed again, and the car its usual 'urgency' straight off and before turbo, you can tell it 'wants' to to go even if revs at idle if that makes sense (for those of you with similar setup)...but doesn't seem anywhere near as eager after the initial 'here we go, get ready sort of feel) before the power really starts around 2k all the way to the end of the range, it goes to end of range but not like it did..
I would say has its urgency as soon as peddle is slightly pressed then a slow gain until 3k where it starts to pull a little (like its trying). I'd say about 20% down on power and more on torque (atleast). I am thinking air system as its like its struggle to breath if I can describe it like that.
Google and searching here, ...MAF. Is it worth me disconnecting the sensor for an easy test? Some are saying it will raise a warning light and this will persist on the dash until cleared - i dont want this for the obvious reason if there is an underlying issue that I am not currently aware of, i wont spot this if light is already on? Oddly enough, the car was down to less than 5miles tank at the weekend and was half filled with Tesco's diesel hich I have never used. Clutching at straws a little and just lookign for a reason I guess, surely wouldn't make that much difference?
The car is going to Aberdeen (from Nottingham) in 2 days and I am going to struggle to get this hooked up to any diagnostics/slot at a garage. Any thoughts on MAF removal to test if its that, please? Will the car go into permanent 'limp' mode until cleared? i could do with going to Aberdeen at a speed greater than ~40mph if the MAF removal causes issues after reinstalling it :biglaugh: Also opinions on returning the car to standard for its drive to Aberdeen until diagnosed? (any point?) Car is 70k miles and I got it remapped at 40k 18months ago. Presumably if something serious like turbo, i would already know about it? Wonder if its a dodgy pipe somewhere, will check later...or at least what i can anyway.
Car has never missed a beat, had cambelt (and water pump) done, all serviced 6months ago, only issue was the EGR(?) valvle blocked 1 week after i bought it and was coked up stalled at busy roundabout and was an AA job:zx11:. Back to dealer and the car had covered only 200miles in a year before I bought it :) Cleaned and motorway blast and all good....until now. Any other easy things I could try before I chance the drive in 2 days :)
Cheers all! :)
