td4 freelander 1

[nickc4]

Hi there,

New to the Forum. In need of some advice please.

I have a TD4 Sport Freelander 1. Been having some small but annoying issues.

Symptoms:

1st Start of the day, quite alot of burnt smoky fuel.
When the vehicle is warm and say 20 mins into journey, when pulling away from stand still, I would feel a slight hesitation at around 1500 rpm then power up ok. At the same time, small puff of smoke.

I have up to now changed:

EGR Valve
MAF
Intercooler hose.



Much better in response but at times still get the hesitation. No smoke now on cold start or at hestiation.


Car was serviced 1500 miles ago back in October. It has since been into 2 garages one being specialist and one main dealer and both cant find any faults.


Any ideas?

Your help is much appreciated.

Regards

You might be better off asking in one of the specialised LR groups like LandyZone. It sounds to me like you may still have a MAF issue. You could try unplugging the MAF and seeing if the pick-up hesitancy disappears - if it does, then you've replaced one duff MAF with another - this isn't unheard of as the standard Bosch units can be pretty dodgy. Apparently the fix is to replace with a Pierburg unit, but then you have to use a gizmo to translate the signal so the ECU can understand it, so it's not something to contemplate if you don't work on the vehicle yourself.

It's probably of little comfort to you, but I have a 2005 TD4 with 65K miles on the clock, and mine has the same pickup hesitancy when it's warm. I'm planning a major service in a couple of weeks, during which I will fit an EGR bypass, a BMW crankase breather/oil separator, a new MAF sensor and one of RoverRon's SynergyII units. Unitl then I'm just living with the pickup issue.

Could be worth searching on the BMW forum as its the same engine as in a 320d isnt it? However as has been said disconnecting the MAF sensor will you if its kaput.

[nickc4]

See earlier post "You could try unplugging the MAF and seeing if the pick-up hesitancy disappears - if it does, then you've replaced one duff MAF with another - this isn't unheard of as the standard Bosch units can be pretty dodgy. "

In which case you should have located the requested step-by-step instructions on LandyZone

Ok cheers. Have been on Landy Zone. Speaking with guys who changed two mafs, Control turbo solenoid, EGR and same issues. It was finally the ECU. So the disconecting the MAF does not guarantee that its the MAF. This was done, changed MAF as it drove better disconnected and then back to square one after spending couple of hundred quid. With my vehicle, mine has gone to several garages who have checked all sensors and mafs, and ECU and still cant find faults.

Am I right in thinking that the only problem that you now have is the pickup hesitancy under 2K rpm when the engine's warm?

Just how bad is it? Have you considered fitting the SynergyII to sort it out?

As I said earlier, mine does it as well (and so do a couple of other TD4s that I know of). When I've mentioned it to other people, they just say 'yeah, they do that sometimes'.

had this with numerous td4's rangeing in age and mileage and it has turned out to be the injector seals starting to leak internally and causing the fuel to run back through the leak off pipes and thus a lack of fuel pressure. Get the injectors leak off tested and go from there

Hi there Gas,

Yes it does and not all the time. Better with new maf though!
