Had the car 5 weeks, keep getting intermitent faults ANTI-POLUTION FAULT, FUEL INJECTION FAULT, ESP FAULT - telling me to contact Renault dealer, These are very intermitent faults but when they kick in, car shuts down or if that does'nt happen the car will act like a turtle and travel at a massive 15mph. Most mornings car is fighting to start and sounds like its mis-firing, if the car starts it seems to be ok, if it does not start first time all of the above faults kick in. They do clear after a period of time, Anyway its booked in at my local Renault garage......fingers crossed

Hello Olaycalf & welcome.

It might be worth perusing some of these posts so you can see that you're not the first to have had such problems with this engine type...it might help you decide whether to throw money at the car - or dispose of it now.

Cheers Paul

Like i put i had it in at Renault and they did find the faults, and as a result they want just over £2000 to fix it, looks like most of the answers on this site are way off the mark, when it comes to intermitent ESP/INJECTION/ANTI-POL FAULTS. Unless im just a one off case, anyway guys the car is going and a new one will be bought defo not a Renault

I must admit to only dipping my toe into the Renault water just the once - and after it was bitten off, I learned my lesson.

Best of luck with your next chariot.

I forgot to mention Renault wanted £2000 to fix just one of the problems the overall cost to fix the skip was just under £3500, when the young chap phoned me to inform me of the good news i laughed down the phone at him when he said do you want us to carry out the work on it, lets just say ive got no toes or feet left now that im walking everywhere. from now on im buying a horse and cart

£3500 to repair it? You an get a pretty decent car buy spending that much - throw the same sum at your Laguna, and you've got a ticking timebomb until its time to haemorrage more cash...

Horse & cart looks good to me, the price of fuel these days.

I have had this problem many times, and have had to call out the AA to reset the computer so that the engine would run correctly.
The Anti-Pol light kept on coming on, the engine revs and power would drop off and end up chugging along.
Having had many diagnostics and going to Renault who charged me for resetting the computer and reprogramming it again (didn't work btw) I stumbled on a simple diagnostic method myself and have pinned the issue down to the Cruise Control Switch adjacent to the gearstick.
When this is switched on and Cruise Control is used, it seems to interrupt the engine management system.
Since resetting the last time, I have not used Cruise Control and the issue has NOT re-materialised.

Where the exact fault lies by combining the Cruise Control and Engine Management inside the computer god only knows but this has sorted my issue finally
