TD4 erratic running on tick over or light load

Neil Roberts · Feb 18, 2019

I have a 2004 TD4 Freelander1. The engine light flashes intermittently and the engine misfires but everything runs fine when the engine is under load. It starts straight away hot or cold but runs erratically when it ticks over. Whats the problem?

Sounds like injectors. You'll need to have the cause of the engine light diagnosed.

Thanks for the reply. I haven't done anything to the engine but over the last few days it's been running fine. Could it be a dirty sensor or poor connection somewhere? How do you clean the sensors?
Cheers

It depends on which sensor you want to clean, and weather cleaning is helpful. There are very few sensors needed or used on the TD4. The main ones are the MAP sensor (can be cleaned with a spray cleaner) and the rail sensor (can't be cleaned). There's also the MAF sensor (cleaning is pointless IMO) and the engine temperature sensors (again cleaning is pointless).

Hi Nodge, Where about's is the MAP sensor?

On the LH side of the inlet manifold, as you look at the engine.

Thanks for that. Will hopefully get to it this weekend.

Another problem Is there an easy way of changing the front mount on the rear diff on my F1?

Thank's for that hd3 I was beginning to think that I would have to drop the sub frame down. For the sake of 1/2 inch more clearance on the cross member it would come out without removing the other mounts. Anyway a job for next week. Cheers
