Hello, patient a6 c5 2.5 tdi AKE problem with firing, not when it fires as normal, and not when you have to shoot for a long time to fire. An example from today I get on, start the car (smokes normally), drive away from 500 m, I go back after 1.5 hours and I have to spin for a while before it...

Diesel fires up to 500 meters? For what ? You will cut the battery (if you have not already done so) in this way. And you are surprised that it fires poorly ... Hold me or I'll let go

It needs 15-20 m of engine work to accept the current it gave up at start-up - just for the news. Although this is not about the topic but ... are you sure that you have a charged battery (after a few routes several hundred minutes after a few such firing certainly will not be - such laws of physics)? Observe how it turns the engine, I immediately recognize that it spins poorly as I have discharged (in addition, the ABS indicator lights when starting). Injection system not aerating?

injection angle to be checked first and candles, fuel filter, injection overflow lines

Also check the wires on the pump that go from the pump electronics to the valves. insulation can burn out and short-circuit. The shaft sensor can also give similar symptoms. Overall, it's the nastiest engine possible. You will do everything and you are still unwell. Somewhere on the Ukrainian forum I saw swap vp44 on VE6 mechanical

Check the glow plugs. Added after 1 [hours] 57 [minutes]: Candles, fuses and candle temperature control.

Well, don't let it go, if nothing sensible to say you don't have why you are littering the subject? I'm not asking what distance I have to cover to have a diesel, but something else. The battery is new, so there is nothing for heavy firing in my case ....

Hello, patient a6 c5 2.5 tdi AKE problem with firing, not when it fires as normal, and not when you have to shoot for a long time to fire. An example from today I get on, start the car (smokes normally), drive away from 500 m, I go back after 1.5 hours and I have to spin for a while before it starts. When the engine is warm, it burns well (1 in 100 fires need to be turned a lot). There are no errors
