Hi :helpme:
I am about to contact the BBC WATCHDOG team regarding the problems with the rcz requiring a decoke.
This is a known problem with this engine as I am sure you all know.

I was wondering if any members would like to put there names to a list, which I could present to them along with my own regarding the carbon build up which lets face it should not be happening to the rcz

And we can see if they can any help by getting onto Peugeot and see if something can be done about it.

As I am banging my head against a brick wall trying to get my dealer to do anything only 40000 on the clock and it needs a full decoke. been going on now for 50 days and still no progress don't think I have any option but to contact BBC WATCHDOG.
Or can someone come up with any other ideas as to address the problem as this will be an on going problem.

Thanks.
Peter Rennie.

Hi Peter,
Sorry to hear your troubles with your RCZ, on the matter of the decoke situation, this problem afflicts all PSA direct injected engines which are currently fitted to BMWs mini, Citroen DS, and of course the Peugeot, the mini fraternity seem to be way ahead of the game regarding decoke. There are quite a few service centres offering a walnut decoke for around £400 this involves blasting walnut shells at the intake valve area to remove any carbon build up, this method is quick and doesn't require the removal of the cylinder head.
There is a system which the mini guys are adopting where the residue that is being recirculated to the intake area is directed instead to a catch tank and must be manually emptied.
Using high octane fuel and longer runs will also help with less carbon build up allegedly.
I don't think watchdog will entertain you to be honest worth a try but I think they will look at it as a service procedure on this type of engine.
Worth a try though, but happily I can say as yet my RCZ engine (24K miles) and my wife's Mini Cooper S (56K miles) haven't suffered from carbon build up.
Good luck hope you get sorted soon.

That's a problem of all DI engines.

As said before, common problem with Direct Injection Engines. Before the RCZ, I was considering a Lexus IS250. Same problem. The idea of Direct Injection is economy, but them, when using a proper fuel, like V-Power or similar, part of the benefit from the cleaning agents, are wasted, as the fuel don't access where the carbon build up. Just as advice, using better fuel grade will delay such problems, as the fuel burn more efficiently, plus the fact you get more torque available earlier, allowing earlier changes.

I have used Shell Nitro V power from day 1 and I also add half a bottle of Red X Petrol treatment to every full tank. I haven't noticed any issues as yet, I'm on @36k.

Hello Everyone

New to this site and I'm not mechanically minded. Bought my RCZ two years ago and loved the shape and performance. Within 9 months I had noticed car not pulling then one day to my embarrassment the car wouldnt go faster than 20 and I limped to a garage. Doser valve fitted for £300 9 month on again its happened again. Reading others queries is it a doser valve or is it a decoke or does this valve decoke. I cant afford £300 every 9 months. Can I use REDEX in a diesal car (dont laugh)

Diesel redex yes.
I'm a big proponent of the Italian tune up. In other words hammering the living daylights out of it.
Especially modern diesels, with their silly emissions control equipment.
Hasn't done any of my Peugeot diesels any harm. Get it hot and kick seven bells out of it in every gear for 20 miles.

Btw, afaik the cokeing issue is on the THP not the diesel.

Was there any message in the display?
The HDi has very few problems. The only common thing to go wrong in the DPF will clog if you only do short drives. You will need to take it our for a longer drive regularly and make sure that you either drive at high speed or with high revs so that the filter will be cleared.

Short slow drives are a killer for direct injection cars. You need to get everything hot and then give a good blast out every so often.

If they didn’t want you to use the Rev limiter, they wouldn’t have put one in there :eusa-whistle:
