Evenin' Gents.
I've been a FrenchCarForum and Citroen Car Club member for over 10 years now and have had various Peugeot's and Citroen's including Saxo's, Xantia's, XM's, C3's, C6's, 306's, 307's, a 406 Coupe and a 407 Coupe. I was advised by a good friend of mine and fellow DS3Club member to post on here to see if any of you knowledgable chaps can help me!
The car I'm having problems with is a 207 GTi, not a DS3. I'm at the end of my tether with it having spent a lot of time and money trying to sort the problems out.
We've had the car for about a year now. It's a 2007 with 60k on it.
When we got the car initially it felt flat and nothing like what we expected it to. Shortly after we got it the auxiliary coolant pump for the turbo packed in, the temperature sensor packed in causing it to think it was overheating, then the high pressure fuel pump packed in, shortly after that it melted it's catalyst due to running lean, and in addition to these it's also had the timing chain, guides, tensioner, sprockets and everything else the chain touches replaced.
After all this work, the car seems to run very nicely, it's smooth, and since having the chain replaced it idles beautifully now which it didn't before. The car still feels very flat though. I've got a Citroen Xantia Activa with the 3.0 V6 engine and a manual box in it, according to the book time of 6.9 seconds to 60 for the 207 it should easily be able to keep up with the Xantia. Unfortunately though it can't get near it. On paper the top speed should be circa 130mph. It couldn't even dream of getting anywhere near this.
There are no fault codes stored in the ECU and when the missus is driving it it behaves absolutely perfectly. When I try and use the power that it should have, it sometimes feels like it stutters and doesn't excite.
We had the car remapped by EcoTune in Hillington and it only made 140bhp on the rolling road and when you tried to accelerate in it the power delivery was horrible. It felt like it was constantly surging and the torque curve on the dyno was covered in spikes. This was done before the timing chain was replaced, now the chain has been replaced it's much better but still not right.
From reading on the internet, a big thing seems to be carbon build up behind the valves. There's a local BMW specialist in Glasgow who charges £300 to do it, but before spending another lump of cash on it I thought I'd ask here in case anybody can suggest anything that hasn't been done. Is the carbon build up likely to cause these problems?
Sorry to be joining and going straight to asking for help, especially seeing as my car isn't even a DS3! We've also got a 207 HDi which we're intending to replace in Spring next year with a DS3 having driven my mates this weekend and being very impressed with it.
