Remapping caused turbo damage on ds3 thp

[Eagle]

A friend of me has a ds3 thp, he only had an ecu remap from a company called revo about two years ago. The ecu remap gave 192bhp nothing else was changed/modified in the car. The guy that owns the car is a sensible driver, always waiting for the engine to warm up before doing any hard acceleration, also waiting the turbo to cool down after long journeys. The only issue with his car was the inlet hose of the turbo, it was frequently torn apart , so the guys from revo company installed a racing type turbo hose, this cured the problem, however about a month ago the car started losing power all of a sudden and the 'check engine' light was coming on. Diagnostics showed that the turbo sensor was giving the check engine, however after inspecting the car at citroen dealership they noticed that the valve inside the turbo was broken and they couldn't change it because citroen is not selling this part alone, it comes complete with the turbo, estimating a price of 2,500 euros to fix it, but also they insisted to remove the ecu remap because the turbo was taking too much pressure and that was the cause of the problem. The car has around 65,000km.
I wanted to ask if any other thp owner had any similar problem? Could it be a case of a badly done ecu remap? if they had installed a forge dv valve and upgraded turbo hoses was the car going to be ok? or its just the turbo too small to hande 192bhp?
If I am going to have an ecu remap for my car as well I don't want to end up in the same situation.

Hi Eagle- intersting post, and your friend has completed a lot of kms on his remap.
I am not aware of any turbo probems on remapped THPs over here, and think the OEM turbos are rated to 220BHP (Some one correct me if I'm wrong). The most reported issue of remapped THPs in UK is that the clutch starts slipping over 200ish BHP, and some pistons/ rods have disintegrated, possibly due to the extra heat or the pistons not being manufactured in a good way. Pre-detonation too.
An upgraded diverter/dump valve may have helped, but not sure.
My last THP was running over 200BHP for 16000 miles and no problems with the Turbo.

Have never heard of a dead turbo on an EP6 engine... have seen a lot of dead pistons after REVO remaps, mostly on mini coopers N14 engines which are the same as EP6... if you want a remap - go to etuners! Stelios's the guy you need! He's from Greece.

Wastegate?

It'll be the shit in the oil pan that's caused it..................

No, regular use of a clay mitt would have stopped this from happening.

More likely electro cooling pump failed and cooked the turbo over time

This unique appears to be certainly superb. These types of really small truth is created utilizing wide selection associated with skills know-how. We prefer the concept a great deal. bk8
