No turbo boost in my TD5 Ideas???

It certainly sounds like the one they have already cleaned.

Something else you can try is to unplug the Mass air flow meter.

When the heavy rain and gale force wind subsides I'll go and have a look at that. Would I expect it to be clogged up or stuck or ?? When I locate it do I just remove it and then go off for a drive without it??

Leave the sensor in place but pull off the electrical multi-plug as per the piccy below (courtesy of google).

There is a piece of wire on the side of the plug. You need to squeeze this in as you pull the connector off. Sometimes squeezing the wire then pushing the plug forward before pulling it backwards makes it easier.




And then start your engine and go for a drive.

When you want to reconnect it, turn the engine off and re-fit the connector and then re-start your engine.

Wow things certainly are conspiring against you derwendolly. Sorry to hear its not as easy as might be for some, youve certainly opened my eyes a bit, as my initial comment was based on you saying you werent so confident with working on cars but I never realised you had so far to go to a garage. Sounds like the td5 is the ideal vehicle for you in the area you live but its a pain that once these things play up it can take a bit of time and trial and error to fix. Ive gone through that with mine and then had over 2 years trouble free. The hire car company age restriction is a bit of a joke. The idea of a cheap runabout could be the way forward, I would have hoped the insurance would be much cheaper than for your disco. If you feel confident in doing some of the tasks which have been well written up, such as what ratty suggested then could be worth trying these before committing yourself to the garage again. Im sure youl get all the help you need on here. At least its is still running so hopefully in taking things one step at a time youl get it sorted soon.

I'm trying to do as advised by Ratty

Yes, the 'upper age limit' to hire a car is a joke when you consider I have owned and been driving big cars for years and since passing my driving test in 1965 have only had 1 claim (13 yrs ago) and that was for my Range Rover which someone ran into when I wasn't even near it!!!! No accidents, convictions etc., not even speeding or parking fines (fingers crossed) and they will happily hire to a young/incompetant person with no quibble. I suppose that is one of the penalties for getting 'old'!!!! When I reached 70, I even took the IAM 55+ driving 'test' to ensure I was still up to scratch and not just thinking I was, and I passed with flying colours - thank heavens!

Thanks for that. Armed with that info., I will try to do it as soon as it is possible and report back.

Something else that's easy to check is your oil level. I have come across low oil levels on td5's causing loss of power issues before.

Do you have a can of wd40 and a pair of mole grips to hand too?

Engine oil level is fine and yes, I have both wd40 and mole grips here.

We also have the most awful weather we have had for a long time! The only thing NOT to have been thrown at us is ....... SUN. I was awakened this morning to a brief thunderstorm and now it has been hail and sleet as well as wind and rain etc!!!

If and when you do get a chance to play, something else you can do is to check the turbo wastegate isn't seized. DO NOT ATTEMPT TO DO THIS WHEN THE ENGINE IS HOT.

Ignore the yellow rings circled in the piccy I pikied off tinterweb.



If you follow the air pipe from the mass air flow meter to the back of the engine you will see the turbo covered by a metal heat shield.

The round capsule (showing above and to the right of the right hand yellow circle) has a threaded bar coming out of it and going to a pivot behind the turbo.

you need to spray some wd40 at the pivoting bit and then lock your pliers onto the threaded bar and work it back and fourth. I find it easiest to lock the pliers in an upright position. You will need to grasp the grips with both hands and push forwards towards the heat shield. ( Mind you crush your fingers against the heat shield). It should be a bit stiff but smooth to push. If it feels notchy or you have to push really hard then it was sticking.

If you test drive your landy between each alteration or tinker that you do, hopefully you will eventually identify the cause.

What a day and what a night! Been out to survey the damage and it seems to be just the tv aerial and sat. dish that have succumbed to winds.

But the Disco, in his new portable garage is fine! Three cheers for German engineering and storm straps.

I am now trying to pluck up the courage to start on the advised checks for my turbo problem.......

Will update when/if I am able to give it a go.

UPDATE

After many wet and very windy days, I set off this morning to carry out Ratty's instructions. I identified the appropriate 'bit' from the picture and then ..................... my husband came out carrying the phone! And guess what? By coincidence, my No1 mechanic asking me to take the car up to him tomorrow as he had just received the ????? ?????? part and he would put it on straight away and leave me to see if it was any better. That is what I call good timing! Although I am a bit disappointed not to have been able to achieve the first simple step of Ratty's guide by myself. I will carefully watch what is replaced as he is still not certain that the problem will be cured.

I hope it is because I am off to France next week for a short break! I do have breakdown/recovery both in GB and in France though!!

Just had this part changed and, although the old one did not looked blocked, the new one certainly seems to have made a big difference - so far. Fingers crossed for my trip to France next week.

A big thanks to all for offering ideas and especially to Ratty who provided me with detailed ideas which, although I did not act upon them, I did understand what was being changed by No.1 mechanic.

What was the bit that they've just changed in the end?

The ''mass air flow metre'' ??? A piece of black 'plastic', about 4'' long that went between the two parts of that large diameter pipe which you showed in the first picture. The bit which had the sensor attached to it.

Yep. The one I said about unplugging.
