Renault Master 2.5 2006 (LM35 DCI 120 2464cc engine number C037703). Only 1 gearbox after 120000. Managed to find a guy in Northern Ireland here, who replaced all bearings for £450.00.
Still OK at 160000. BIG problem is the fuel situation; constantly cutting out on long runs. Installed a new fuel injector rail £260.00 yesterday and fuel filter. My guy is on the road from Belfast to Dublin today. He has rung to say it has cut out 3 times already. Does anyone have the definitive fix for this problem. Before I waste more money on pumps etc.
Or is it an engine management problem.
It does sound like an electrical fault somewhere, but being intermittant, it'll be hard to trace. I would start at the pump and work from there.
I have a Renault Master myself (2001, T35, 2.8dti). Other than general wear and tear, it has only let me down once in 6 years (blown ECU and a knackered pump).
I took it to Reg Vardy Renault to get fixed, they put a recon pump, new ECU and coded it (this was after 2 weeks of, and I quote the mechanic... "a nightmare"). This cost just over £1300. £525+vat for the pump, £360 or so for the ECU and coding, + misc... The rest was labour.
Very happy with that. They get my custom again no problems.
There seems to be a weakness in Renault gearboxes. I am on my second Master van, and both had gearbox troubles in around 90.000 to 100.000 Kms. Is this a stock Renault fault?
I own a Movano 2.2 on a 53 plate. Seems possible to me you have a problem with the EGR valve? Lots of problems with EGR valves! Mainly diesel, worth trying, cutting out and losing power, usual symptoms... Dave.
Hi. I have a 2001 year model, exactly the same symptoms. It has cost me a fortune with so called specialist diagnostic garages unable to pin point the cause unless I leave them my cheque book. It has got worse recently, but sometimes is okay. I would be grateful/interested if you had yours fixed or the problem diagnosed. My tel 07988677878. Regards, Colin.
I love reading all of these comments, as I have just bought a 2005 dCi 120 van, and the clutch has just started slipping slightly, and looking at the service history, it was only changed 35k ago!!
All these repeat problems are awful, and Renault really need to get on top of the issue, and consider a recall for these vans, especially the gearbox problems; they are clearly designed poorly.
Prior to my dCi 120, I had a Citroen Relay 2.2 HDI. This developed the driving up a hill and cutting out issue that seems to only happen on french vans; do they not have hills in France??
Anyway, it turned out to be tiny metal particles that had passed through the fuel system and got caught in the fuel pump; needed a new pump fitted and lift pump. The metal particles had originated from and sheared off the fuel filter screw thread, and all this happened shortly after I had the van serviced. I just thought this may be useful information to someone who has a similar problem, as I am sure Citroen / Renault are similar in design.
Had the same problem. Could get no more than 65 on the motorway. Would not go up a slight hill, even in first gear. Airflow sensor was fitted, cost £125. Now does 90mph and goes up the hills in 5th gear.
I bought a 2006 Master 2.5 120 HP 6 speed, with 92k miles. Now the gearbox has started to rattle badly. The only option is to replace the bearings or buy a new box. Clearly a major fault by Renault.
Also, the wipers now won't work on intermittent setting. Seems to be another common problem. £150 for a new wiper motor.
