THP 155 Engine Hesitation

[Dangerousfish]

Last time I went in with the problem, I explained what I thought the problem was and took an info rapid in for cylinder head cleaning. They politely pointed out that it was for a different engine to mine! Even though I knew it was for the THP150 and mines the 155.

Any idea how else I can convince them to check this out? It begrudges me going and paying for the work done, when I have a car under warranty with Citroen.

Maybe try asking them to look up the issue on the forum whilst you're sat with them? Take a note of the thread ID and go from there?

Have you tired the BG K44 additive Chris
As SFG says, if its under warranty, you will just have to do what they suggest, but keep pressing them

Maybe whizz up Jamies and let him have a look with his camera
And get a walnut blasting perhaps

Are you running decent fuel?
Havent looked back over the thread, so sorry if these questions already been raised

Hi Chris,

BG44K used twice since I've owned the car, the most recent was two weeks or so ago. Only ever run the car on Shell - again more recently only use V Power and have used 3 or 4 tanks full.

The only thing stopping me approaching a specialist like Jamie is my warranty, I can't justify spending on problems that should be fixed by the manufacturer.

Thanks for the advice.

Might try that one! Thanks mate

I'm pretty sure the engine isn't that different but the symptoms are the same. You certainly shouldn't have to pay for anything, however I suspect you are on a well trodden path which will result in them trying various options that will ultimately prove futile.

I did try to explain the engine is very similar and that it could at LEAST be ruled out from their point of view - service lady was having none of it.

Thanks for your input

Quite agree- Ive got 2 year left on my 155s warranty
Just wondering what I would do if i was you- i would seek Jamies advice, and probably ascertain (Camera) whether walnut blasting to get rid of the carbonisation which could be caauing the detonation issue, is warranted. Would try 2 or 3 times with CUK for a while, then do my own thing TBH

Wish you luck

Yeah seems this is my only option really. I don't want to just "get rid" of the car and associated problems, and at this stage it's not really a major one in my opinion, I.e it doesn't affect my driving of the car regularly.

Thanks

Could be fuel pump HPFP
But sounds like detonation

Cars booked in for Wednesday - any more advice in what documentation/evidence I can take will be welcomed

Car has been dropped off this morning - curious as to what they say when they call me to say it's ready!

Maybe your engine mysteriously has got "dirt" inside it too..

Update on my car:
Did around 400km this weekend, with lots of fast driving on a trip with my mates. My DS3 vs RR Evoque (150hp diesel) vs Subaru Legacy (150hp diesel). The car showed no hesitations at all.
One strange side effect since it's been in service: the temperature indicator is a bit to the left (cooler) side. Before it was always straight in the middle.
Will be driving another 400km this weekend (to the WEC in Francorchamps and back), so I'll be giving the car another test session.

Glad to hear it's seemed to have solved your problem.

My dealer has had to order in the cleaning agent needed to clean out the inlet valves, as my car was showing the Super knock fault code.

At least they've admitted there is a problem, and are doing something about it

What cleaning agent Chris?

They didn't say! I'll ask when I take it back
