Renault DCi 1.9 fixes.

1.9 DCi /cdti
Has most people miffed and a lot of trash clueless talk on line when you need a answer.

Wiring diagram is almost entirely pointless, they have a few different looms and the colour doesn't even match or even the pin outs...
The wires do not have a constant, so you may have switched colours along the loom.

A TD has a real basic function.
Air and fuel makes bang bang.

So you have fuel and a filter then a pump and a regulator. Reading 3ohm +-.5 ohm.
The regulator works from the ECU and rail pressure sensor.

That's one system.
The next is the Injectors and glow plugs.
The injectors I'll leave out as they can fault in a number of ways. See leak off tests.

The next side is turbo, the sensors (map and boost) and I should include MAF.
The most common fake is the read out. A 44mg/h but the loop back normally shows a fault so fault, while basic mec's will say it's working.

Hope this helps.

my mechanic used to work for Lucas. and he has told me never use non OEM parts for these Renault engines, after some other garage put a cheap MAF on and made it idled at 3000rpm...

Hi Rory

I recently bought an Opel Vivaro 2005 1.9 DCi that has been turned into a camper van. However it's in limp mode with several OBD codes. The engine needs some revving while cold starting, otherwise it shuts off. When revving for about 30 seconds or so its running stable in idle. No weird noises or knocking sounds from the engine. As previously mentioned it's in limp mode and it's hard to go above 40 km/h. The transmission and clutch seems fine and is working properly.

The OBD codes that I get with my cheap OBD-reader is:

P1814
P1815
P1829
P1802
P1806
P180B

What could be the cause behind these fault codes and how should I proceed to troubleshoot and diagnose the symptoms?

Help is much appreciated!

Hi rory, cheers for vid..i have a renault master 2013...was driving fine but to keep it brief, now no dash lights except odometer, .vehicle obvioisly wont start. Battery good, engine strong..all fuses and relays seemigly checked. Ecu not giving any reading. Its been at mechanics a while now and im just trying to find a solution....anyway.. Have you found that it is a common issue for one of fuses on battery to "appear" good but is actually broken. I.e. there is just enough of a connection to give a good reading on multimeter but the fuse is actally corrupt. I have read a couple of comments tbat this was the case and seen couple videos aswell so wondered what yr thoughts were. Any other suggestions appreciated thanks again👍

Hi Rory. My 2.0 Renault trafic stopped shortly after a normal start. It cranks fine but the glow plug light won’t come on again. All glow plugs tested ok for both resistance and 12V powered. ECT correct resistance. All fuses and relays fine. Any help appreciated 🙏

You help will he highly appreciated

Great video mate. I have a vivaro LWB 2.0 2012, and I can't get communication with ecu, I can connect to bcm, test light, etc. Before I have DF015 main relay control circuit short circuit to hearth. Did you knowthis relay location?, and df25 preheating unit diagnostic connection fault alerted via the control unit. Now I only have error code DF067 injection multiplexed emission missing . Thanks

Hi Rory, I have a problem on my Vivaro 1.9 74kw. Throttle pedal no reaction when engine start. Idle speed is little bit lower then normal but after few seconds engine speed start getting higher and throttle pedal start function normally. is it possible that they are bad injectors? MAF sensor, pressure sensor both are new. EGR valve is clean. Turbo is good. Car starts perfectly in every temperature.

Hi, Do you know much about the limp mode fault when hitting 50/60mph? Absolutely fine until you hit that speed, if u turn the key off/on its then fine until you hit 50/60mph again? Thanks.. 😊

[avfcs]

Hi rory, have a issue with my 2004 vauxhall vivaro, 1.9 diesel, no eml light on ignition. Plugged in code reader, doesn't pick anything up, says no modules or something similar.runs fine though, sure previous owner as turned eml light off some how, any advice greatly appreciated, thanks mark.

hi mate i have a question. i have a 2006 trafic with 1.9 engine. when i go full throttle the car feels like it doesn't want to go and i dont get power. also it cuts the power regularly when full throttle. i am thinking that the fuel pump is faulty. what is your opinion?

[acewelding]

Hi Rory, I have a problem with my van not revving immediately when warmed up, it idles but takes a while to start revving. Any pearls of wisdom would be appreciated as I took it to the local dealers and they said fuel pump.
