2001 Renault Clio Dymanique 1.5 turbo diesel from UK and Ireland
I have a 2001 Renault Clio 1.5 diesel, and have have problems with running smoothly and starting issues.
Renault were not very helpful, and did not fix it after the £65 cost to put on their diagnostic tool. It came up with some problems, which were cleared, and they said if it persisted, then they would look into it further, no doubt there would be another £63 for diagnostic before they even started.
Although the running problem has rectified itself, I'm sure I narrowed it down to a very dirty EGR valve. Take of the airfilter and you will see a sound thing sticking out above the turbo, 3 10mm bolts and pull it out. Plenty of WD40 and kitchen roll, looking back rubber gloves would have been helpful as it's that really sticky black grease gunking it up.
As described in many comments here, I have also had a starting problem where more often than not the heater light would not light up, but after several turns of the key it would work. So I cleaned the 3 little black relays under the bonnet on the passenger side, which were corroded, and used a small nail file in each hole the relays sit in and it work for a short while. I think the left one is the heater plug relay, middle is the fuel pump, and the right relay is the starter motor.
So I swapped the heater plug with the starter motor relay, and the heater plug lit up every time, but it would not start, so although the relay was clean of corrosion, I think it must be corroded inside, so I'm off to buy a new one on Monday. I've read on this forum that they cost about £15.
In short, if you have this problem, don't waste your time and money at Renault, and try these 2 things, it could save you a bundle as most comments here say that Renault think it's wiring loom or throttle body.
The car is general a very good car, it's just these few problems that let it down, and Renault have no idea about. They seem to try the most expensive thing first.
Would you buy another car from this manufacturer? Don't Know

Just cleaned out the EGR valve on my 1.5 DCI & what a difference in performance. I bought the car the other day & found it to be very sluggish & a bit lumpy, so upon your good advice here I cleaned the EGR valve (very easy job by the way, if I can do it etc etc). It was all sooty, a small tip for anyone doing this job, there are 2 moving valves in the unit, make sure that you jam one of them open so as to clean the other & vice versa, it's self explanatory once you see the valve. Also it can be a little tight to come out of the housing, so you might have to price it out slowly.
The car is still a bit lumpy on idle, but 100% improvement on performance & I can live with that.
Thanks for the advice.
