Hi,
For about the past 18 months I've had some weird issues with the performance of my R26.r.
Symptoms include:
1. Boomy exhaust noise
2. Disappearance of whoosh in cabin
3. Lack of power
4. Increased full consumption
5. Weird gaps in exhaust sounds when accelerating hard
I've had it into Renault three times now and they've done the following:
1. Replaced knock sensor
2. Replaced solenoid value
3. Replaced oxygen sensor
4. Replaced injectors
5. Told me I'm just used to the car so go away (not directly of course)
Now that the warranty has expired I've taken the car to a specialist whom within 10 minutes agreed the car has an issue. On the dyno the car made 200hp as standard and 216 with the stage 1 map loaded. Clearly something is wrong. I would have noticed an instant loss of so much power so I'm thinking the problem is one that has slowly become worse with time.
The guys did the following to diagnose the problem:
1. Boost leak test
2. Bypassed solenoid value
3. Removed/bypassed actuator (should have given crazy boost but nothing).
I think boost was maxing at 0.3 bar maybe.
They've told me until they can have the car for a 1-2 days it might be the following:
1. Clogged cat
2. Mal-fuctioning wastegate
3. More serious turbo issues
As I'm not hugely knowledgable regarding engines I thought I'd ask for some advice here first. Either tomorrow or Monday I'm having a decat as this is the cheapest of the possible causes to remedy. Obviously if that's not the issue the costs will rise quite quickly.
I've been thinking of going down the forged engine route with a larger turbo etc. So I'm thinking I'd rather put the money fixing the current issue into upgrading the car properly.
Does anyone have have any suggestions and as the problem was investigated by Renault well before the warranty expired should I speak to Renault UK ?
Thanks,
Matt
