fuel economy down after repair...

[johnnybrighton]

I had a crash in my 05 1.4 16V, took off in the air a bit and damaged the front suspension and steering unit and bumper.

I've had the car fixed on insurance (non fault claim) the car now sometimes stalls when pulling up to a junction and taking it out of gear, occasionaly it stalls and all the dash lights come on then it picks itself up again! also it wont start first time now and then.

before the crash it started 100% first time all the time, I have all servicing done by Renault (on 22,200 at the moment). Looking at my on board computer my avg mpg is down to 29.1mpg even after i reset it and am driving very economicaly.

Before the crash i was getting 35+ mpg and that was with me not paying attention to how i drove. I'm using shell vpower fuel as always.

I looked on the repair report to see what the replaced and they replaced the ecu, but on the top of the form it says model 1.2 16V extreme when my car is definatly a 1.4 16V extreme. Could putting the wrong ecu in be causing this poor mpg and start/stall problems?

Was it repaired locally in Brighton???

Not that this helps I know, just curious...

 

[johnnybrighton]

yeh at T Reeve & Sons

(insurance company said i had to go through them, if i wanted to go elsewhere i would have to get an estimate then have someone sent out to look at the car etc and i needed a car for work and uni, i get a [FONT=&quot]courtesy with my insurance)

My friend has his car repaired by them... Took a few weeks, but he was very happy with what they did. My cousin also had his repaired there and again very happy with the work.. Havent heard anything bad about this place at all.

Have you phoned them?

 

[johnnybrighton]

i'm going back tomorrow as they were waiting for the lower front spoiler on back order, i'll take it up with them then, otherwise the work done was excellent!

T Reeves do have a really good reputation around Brighton we deal with them a lot and the people up there are generally very clued up on everything. I'm sure any problems you have they will manage to sort it!
Hope it all gets sorted for you!

 

[johnnybrighton]

thats what i've heard, there good. when i go there tomorrow i'll tell them that my economy is down.

but if anyone could answer if putting a 1.2 16v ecu in instead of a 1.4 16v ecu would cause poor fuel economy etc..?

cheers

They can't have put a 1.2 16v ECU in it as they use completely different management systems. The 1.2 16v uses Magnetti Marelli 5NR management (iirc) and the 1.4 16v uses Siemens Siruis 34 management, so afaik they can't have fitted the wrong ecu.

Doesn't mean some other parts haven't done fitted incorrectly though. What model is it? A dynamique?

 

[johnnybrighton]

its a 1.4 16v extreme 05plate

 

[bmh.01]

Right, i'd just raise it with them then. Does it feel any different in other ways? Handling? Performance?

 

[johnnybrighton]

not as nippy as it used to be, doesnt pull as well.

 

[bmh.01]

You got a list of what was changed? Just trying to think what parts they could've fitted wrong that'd fit (if you get what I mean). Did it have a new exhaust?

 

[johnnybrighton]

im at uni now, list is in the car, i'll type it up when i get in. the exhaust wasnt changed as far as i know.
