996 Complete Power Loss >> Details inside...

On Monday I had my '99 C4 tuned at Paramount Performance. The mods consisted of ;

-Lowering Springs
-KN Cold Air Induction
-ECU Remap

This evening I took it out for a spin to see how it ran. I let the car warm up first, then when the conditions were right I footed it. After about four or five seconds of mashing it the Engine Check light blinked on and off constantly for about 10-12secs. Moments after this, there was a complete power loss. The car idled but there was no throttle what so ever. I rolled to a stop.

After this, I switched the car off for 30secs and thn switched it back on. It was fine after this although I didn't dare floor it again. Any ideas?

All responses appreciated.

That's exactly what I'm going to do. I have a feeling that they may have screwed up the Fuel/Air ratio, as this is one of the things that they adjust when doing a remap. It can cause misfires, which must have lit the Engine Check light up, and loss of power, which happened moments later. I'm going to give them a call and see the response. I'll reply with details...
 
Ditto. Hope they sort it out OK. Out of interest, what increase does such a change make to one's insurance premium ?

Erm, nothing. If anything insurance wise comes up, just re-install the original filter. [8D] The mods really do make a difference though, sound and performance wise! Well worth the money (if they sort this out!). One thing not to get done at Paramount is anything to do with shocks or suspension, they really didn't seem geared up to fit the lowering springs. It turned out that my rear suspension was fine but that both my fronts needed replacing. +£800! After that they just used brute force to install the springs and put the parts together, hammering away and crowbarring parts. Told the Performance Manager that I wasn't happy at all, so hopefully he'll sort something out on the financial side.
 
I got a bit carried away there and went off of the subject! I called him and told him what happened, he seemed very concerned and wanted to come to my house and sort out the car. I just told him I didn't want that, so I'm going to treck up there on Saturday and get it sorted. One last thing that may be interesting... The dyno results. It turned out at 243.7whp stock. Have not yet got the bhp after as an M5 screwed up the dyno.
 
One thing you have to be very careful with the K&N filter is not to over-oil it, otherwise it fries the MAF sensor. If they have got the mapping wrong enough to be causing a CEL, I would be very wary. Are Paramount Performance anything to do with RSJ? They must share the same building. I hope it wasn't RSJ's bods who fitted the springs in that manner.
 
Paramount are next to RSJ but nothing to do with them buisiness wise as far as I know. Richard, do you reckon that it has been over oiled then?
 
ORIGINAL: Richard Hamilton It's a distinct possibility. Lots of reports on RennTech.org on the subject.

I know I might be asking an idiotic question, but does the filter have to be oiled then? If so, how often?
 
I would imagine at normal service intervals, but I'm sure K&N will have a recommentation. They do a special oiling kit and you need to be really careful not to overdo it. From what I've read, once the oil mist gets onto the MAF, it's toast.
 
Ah I know what you're talking about. Without the oil it will not filter out the dirt and dust etc. But I have something called a 'K&N Drycharger', it's a sleeve that goes over the filter head that appears to stop dirt and dust itself... But if it was overoiled, would it really cause a complete power loss?
 
The regular K&N filter is a similar physical size as the standard 'paper' filter, and is a direct replacement. That's what I thought you had. I realise now you have the cold air intake kit. Does it have an oiled cone filter? If the output of the MAF tells the DME that there is no air going into the engine, then yes, it will do strange things. That could have been the cause of the flashing CEL. Switching off and restarting might have reset the system.
 
Thanks for all of your support Richard - I appreciate it. Yes, it's the K&N 57i Cold Air Induction Unit. It has an oiled cone filter with a K&N Drycharger sleeve over it. Do you reckon that the MAF Sensor is shagged? Or will it be ok if I dry some of the oil off of the cone do you think? Cheers Paul
 
Paul You really must tell your insurers about any modifications. If you do not there may be a umber of consequences: - 1. Your insurers may refuse to cover you in respect of any accident damage to your own vehicle or any other vehicle. 2. You may not be able to get insurance in the future if the company discovers that you have not informed them - and might share this with other insurance companies. 3. You may be uninsured and this is a criminal offence; with a fine, points and possible disqualification if you are prosecuted. 4. How much will you save from non-disclosure against not having to worry? Just obey the law, you might think that it is an ass, but you can sleep better if you play by the rules.

I'll take that on board, cheers.
 
Paul I had some work done on my 01 C2 including the K&N induction kit you refered to. I had to buy a new sensor which was located near/on the exhaust (exhaust boxes changed as well) sorry but haven't a clue what it was called, this was as a result of a warning light showing (again don't recall which one it was) [:)] My local Indi changed the sensor and haven't had any problems since (no remap). Informed my Ins Co of the changes and they added £20 ish to the premium!!!!!! Don

That'll be a Lambda / Oxygen sensor. They detect the presence of unburnt fuel in the exhaust. If the ECU can't compensate by making the mixture leaner, the CEL will come on. On the K&N 57i kit: they're notorious for destroying MAF's. Loads of people on VW forums have had the same trouble.
