225 2007 RS 225 new owner really need help and answers!!

I am sure you will get a deluge of replies telling you this shortly, so to beat the crowd...

Have you plugged the car into a code reader yet? First step is to check any fault codes are stored. Ideally, the best code reader is Renaults CLIP which any good Renault garage should have. If that's not an option then any other good OBD2 code reader will give you a head start on the fault codes stored.

This should always be the first step in figuring out what is wrong with the car with a not-so-clear problem like this one!

 

I'd take a guess at a coil pack starting to break down with the heat if the engine when it's been running a while, although as ewant said a fault code reader will stop you guessing.

The turbo whistle is normal it's a characteristic of the car Iirc it's down to the centre section on the exhaust

 

Just noticed your in Saudi arabia, its not the actual heat causing the engine to pull timing or anything?
If i were you i'd either buy the torque app and a ELM327 obd interface (will cost around £15-£20) if you have android or the apple equivilant, think its dash command and a wireless not bluetooth obd interface. Or a datalogger of some sorts to monitor the intake temperatures and what not as i'm guessing its above 40 degrees at the moment out there?

 

If it was a sensor pushing the timing out (like the knock sensor), it should throw an error code.

This problem is beyond me tbh..

 

But if it's on the standard intercooler and its got a cheeky remap you don't know about from the previous owner it may be making a lot of heat it can't deal with and is gradually heat soaking till it can't cope? As stage 1 remaps over here heat soak badly on the dyno on the oem intercooler.
Just a thought as you said you were unsure if it was standard?

 

If it is heat soak then you can monitor the IAT (intake air temp) with an OBD2 reader and an app like Torque on Android.

 

You can also check the boost pressure with Torque. If it reads peak boost over 1bar then I think it has been remapped. Typically a remapped car over here will read 1.1 bar peak boost pressure.

 

Salaam Brother.

You running it on Mumtaz , or Jayed ?

 

I think that could be the problem. The mumtaz in the gulf is better than the jayed , but its still not the greatest. The car should really be run on 97+ RON.
I wonder if it is hesitating and pulling the power due to the fuel quality.
Where abouts in Saudi are you ?

 

I would also check the plugs.

 

Surely the car would have been mapped to take into account the difference in calorific value prior to import? Or am I assuming to much!

 

You would have thought so right ? The gas in the gulf is so much different to the Euro regions. For instance you dont get vapour on the Gulf gas. It also doesnt smell when burnt.

 

This is true, however you will note other than the newer cars they are all NA. All the imports are tuned and mapped. All the yank stuff is used to lower grade fuel. The gas is quite different from Euro gas, so I think it is to do with it.

I know Dammam , well , just over the causeway a lot better. I have friends who work in Dammam.

It might be worth a trip over the causeway to EKanoo garage to get them to have a look. They have some talented workers there.

 

I'm guessing that they must add something to raise the flash point because of the heat, less vapour less chance of it going bang on the forecourt?

 

ekanoo are quality.

I know of bd-design. Abdullah is very good as well. They are in Dammam. Just of the Dammam-Khobar highway

 

You're a brave man driving in Saudi. I've done some work in Riyadh scary driving isn't even scratching the surface!!

 

I frequent the gulf a lot. I also have a lot of contacts in the Gulf. An awful lot

 

Just out of curiosity , which plugs did you change to ?
