Hi Dtac.

I don't think you cleaning the throttle body had much to do with this, if the butterfly valve isn't sticking and the boost sensor isn't chucking out turbo overboost warnings on the dash, you should be fine... From the symptoms you describe, it still sounds suspiciously like a MAF sensor rather than anything mechanically complicated like air leaks, injectors or stuck valves, I looked up the fault codes on your list and it offered this...

Hi guys
I am desperately looking for some help or guidance, the other day foolishly or not cleaned the throttle body out with some carb cleaner since then the engine has been suffering with a misfire or similar. It appears to be only from the bank on the drivers side.
Obd fault codes are:-
P00bf
P2621
P0102
P010c
P0107
I have replaced the throttle body and coded that into the car
Smoke tested the manifolds throttle...

As D5's get to 7 years (84 months) old, they usually appear for sale at attractive prices. Mine was very attractively priced for that reason. 7 years old and 75k miles...just on the cusp of timing belt renewal time when I bought it.

The Bling Barge cost me a bit less than a 2016 Disco 4 HSE I was considering to replace my old and hard worked 2015, 285k miles D4. The D4 HSE that caught my eye was in similar condition and mileage (but with tons of after market extras) to the...

It's 2018 with 60000 on the clock.
So the previous owner decided to save some money and take a risk last year by not doing the belts.

Has it been serviced following the recommended schedule? If so it will have had belts at 84m or 110k.

I have run some silicone along the rubber gasket / glass joint on the inside while applying some outward pressure on the glass to open up the gap a bit. I dropped the front section of the headlining to make it easier to get at. I’ve also run some silicone into the channel between the windscreen and roof. I know that’s not the primary seal but I know part of it has perished and it does contribute to preventing too much water getting to the man seal.

I look forward to using the forum to ease me into D5...

I replaced the water pump and the 2 main camshaft pulleys, the camshaft pulleys aren't really necessary but a pair only cost an extra £125 over the rest of the parts.

That's 3 belts (FP belt, main timing belt and auxiliary belt), a water pump and 2 camshaft pulleys. Besides the idlers and tensioner pulleys, that's about it for a timing belt replacement...

You do have to lift the carpets to get them dry, otherwse it would take forever. On th eplus side it doesn't smell damp. Out of interest what have you done to prevent water getting in on yours?

Gosh I feel very fortunate that I spotted mine quite early. So far no electrical issues and I think I have the carpets dried out. I removed the kick plate on the passenger side and wedged something under the carpet - keeping an air gap open to help things dry out.

I think so, the problem is that it takes forever to get the carpets dry and so it' s difficult to know. At the minute I've taken the dehumidifier out and I just have some kitchen towel under the carpet. It doesn't get saturated but there is still some dampnest there. I think it is from the previous leak. I was going to reseal the windscreen with polyurathane but decided not to. The water shorted out the battery which I have replaced and the SOS system now has a fault, I am assuming that is...

When I had mine done I was recommended to replace the water pump as it is know to leak after a certain time and since you are taking most of this off anyway………

Any other thoughts on jobs to be done at the same time?

Eg. How is the water pump driven?

It actually has two belts that need replacing.

One timing belt, and then one belt at the back for the HP fuel pump.

Note: on the 3L tdv6, the rear HPFP is also “timed”. It won’t kill the engine if not timed properly, but it won’t run as well as it should.

For make… I think mine was dayco.

Hi All,

The car is 8 years old, done 65,000 miles.

I guess I need to replace the timing belt.

Couple of questions:

It's the tdv6, does it only have one belt?

On previous cars I've always bought timing belt and water pump kits, is it a different setup on the disco 5, I can only see kits with one belt, 3 pulleys, no replacement bolts or water pump, which I had expected?

What brand belt is...

Hi Everyone, Newbie alert
just acquired 2018 commercial, all good but the tow bar release key is missing, and the Tow bar is deployed, how can I remove to stow away, local independent said to simply remove pin, twist and pull the knob and hey presto!

What pin?

I imagine the tow bar has been in a while and as such some corrosion will have taken place, expect this won't be easy but any suggestions?

Many thanks
