Nah I dont mate, fairly new on here so best bet is to check the for sale section and/or ask in the wanted section Smile

As regards the ICV, do you have a breather filter attached to it on that short section of pipe? If you do make sure its not restricting the airflow.. this was the problem I had and although my car still feels like its holding back, when I had the breather filter fitted it was absolutely horrific, completely gutless!

I'm pretty sure my problem is the MAP sensor or at least sensor/electrical related, to the point where you can almost feel the ECU receiving duff readouts! Its definately not mechanical as such as there are points throughout the rev range where it just takes off and others where a moped would pull away from me Blink

The only thing I still cant get my head round is how, when it does start hesitating, it still revs up smooth and fast.. just doesn't put its power down? Infact all the symptoms of a worn clutch, just without the burning and unmistakable slipping feel/sound?

Offer still stands for any local "6" owners to come help me source the problem, beer and cash waiting ftw Big grin

I fear this may be the same for me Sad

Is there any way of knowing, before it actually starts noticeably slipping?

interesting you should say that actually as i have also noticed my biting point is right at the top of the pedal? and when i let off to change gear, it sounds like im riding the clutch for a split second even though my foot is off completely? Crazy

sound like a new clutch??

Hmmm... I'm thinking this may be what it is
Would be the first time a clutch has gone on me without the burning smell.. but hey its the first french car I've owned LOL

Cleaning the MAP sensor every few days is helping a little, though I think that could be a seperate factor adding to the problem Sad Thing is, with my limited mechanical abilities, I'm gunna need a garage to do the clutch.. and thats a considerable amount of money to pay if it doesnt fix the problem Sad

it would seem silly taking the box off with no proof it is the clutch

Matt just have a couple of things for you to look at:

1. Thottle position sensor
2. Lambda
3. Engine temp sensor
4. Cat hasn't collapsed
5. Aux belt pullies, alternator, PAS pump spin round ok with no grinding
6. Does it have new and the right engine and gearbox oil
7. What exhaust and air filter?
8. Plugs all ok?
9. Could be dirty injectors
10. Are you sure you are getting full throttle and cable hasn't slipped - you might just be getting

Also, now that you have mentioned the engine temperature sensor... I have noticed that my car doesn't really heat up to what I would call normal operating temperature (90 odd degrees) unless im sat in traffic... on a 5 mile run to/from work it barely rises above 70?

Could that be a factor?

Ok a quick update... have replaced the MAP Sensor and temporarily re-routed the breather away from the throttle body until my catch tank arrives... and so far so good.. car is definately smoother and pulling harder BUT, when only slightly depressing the throttle it seems a little hesitant and like it wants to surge but cant.. as soon as it hits 30% - 50% throttle it absolutely flys.... throttle position sensor maybe??

got a rallye that was doing same thing and it was map that was main fault but also needed to fit a knock sensor as it had damaged cristals in knock! also coolant temp sensors are a massive prob - i was a peugeot tech for 7 years so hopefully this may help Smile

Nice one thank you Smile definately a big help, for the price of them I was planning to replace the temp sensor regardless but the knock sensor.. where is that located and is it a simple DIY job to replace for someone with very limited mechanical knowledge?

Sounds like the lambda to me... this was my problem with it hesitating and lurching but fine at full throttle Thumbs up

Yes very probably - mine did exactly that before I changed the TPS. You'll be getting through fuel quite fast as well i'd have thought.

Nope, crank sensor works by sending a signal to the ECU when a 'tooth' from the flywheel goes past it.

Knock sensor would be detecting a pinking noise to allow the ECU to back off the ignition advance, although not 100% sure if these have got one.

Just made a horrible discovery.. while browsing the forums at 4am this morning (the joys of working nights) I discovered a thread where someone was describing how their 6 resembled the noise of a scooby. Turned out to be compression loss in one of the cylinders and alarm bells started ringing..

My 6 is producing a scooby-like roar under load and although its not using excessive amounts of oil, as I've mentioned earlier, it is breathing oil back in to the inlet to the point where it clogged the MAP sensor. Coupled with this power/torque loss all things are pointing to compression issues so can anyone arm me with possible causes and estimated costs before I go scaring myself!? Sad

IMHO you might want to consider buying a compression tester (Halfords sell em) and carry out a test yourself to see where you stand first. Once you have the readings the experienced guys on here will have a better picture of your engine, and hence be able to advise more accurately.

When carrying out the test make sure you follow proper procedure with regard to the ignition and fuel system first, there are a number of guides on the net.
