Xantia Activa Overboost problem?

[bLuLine]

Ok, on that website you sent it says it comes with Diagbox 7.62..

One question, my Xantia is and end 1994/1995 X1 model, is that going to be a problem running the lexia ? Im asking this because in all the lexia ive seen selling they say something like: Works on all vehicles 1996 till present.

I cannot answer that question, as I have not used my Lexia on a series 1 Xantia. I would hope that somebody who has can let you know. Sorry about that.

[bLuLine]

No problem, you already helped a lot about the lexia
I will research more about lexia and X1 xantia

Any Lexia should talk to an S1 Xantia with the 30 pin Diagnostic socket but you will most likely have
to purchase a 16 pin EOBD diagnostic connector to 30 pin diagnostic adapter...

I would recommend you purchase a Lexia from a vendor who offers this adapter either as a part of the kit or as an optional extra rather than buying an adapter from a third-party.

Reason I say this is some third-party adapters don't work with certain Lexia kits. If you buy it as part of a kit then you have some recourse if it does not work as expected.

I can tell you that the Easy Diagnostics kit has that adaptor (well, mine has).

[CitroJim]

That should be OK then James. Is Easy Diagnostics the outfit with the good reputation around these parts?

[Hell Razor5543]

Apart from the price. They are not the cheapest, but they do seem to have a good aftercare support service.

[CitroJim]

Better to pay a bit more for good service James

[bLuLine]

True i don't mid to pay a bit more and be sure the product in this case lexia will work properly and get a good service..
Will probably buy from that site James posted.

I have now, after James pointed me to it!!!

James, you are right about the ECU and boost levels...

If you are running the standard boost regulator and NOT an after-market manual boost controller then your problem is very likely to be the wastegate vacuum pipe has a hole in it... This will result in no control of boost pressure and the symptom you are experiencing.

The hole (or more likely a slit or crack) will most likely be found at the wastegate end of the pipe. It is not easy to see or check.

Hope that fixes it for you

Hello i have good news
It was not the vacuum pipe it was the wastegate actuator, 4 years ago when we sent the turbo for repair someone opened the actuator to the max so the turbo was always on max pressure.
I went today to a citroen expecialist and he noticed this problem, then he closed a bit the gap so the wastegate can have room to regulate the pressure. Car is now running at 0.5 ~ 0.8 bar and yellow light is gone

Now i can sleep at night knowing this problem is fixed i will focuse now on restoring the other bits of the car that need to be done

Thank you all for the help i will continue posting and later i will show some photos of the activa

[Hell Razor5543]

Well done for getting that problem sorted. Now you can enjoy the Activa properly.

Excellent, that is good news indeed

very pleased to see it's all resolved...
