my moneys on the o2 / lambda thing but it could be lots of things is the problem

they should be able to test the lambda thing using a scope - it should switch quickly when warm (well something like that!)

good luck and let us know how it goes

Just joined and trying to work out how to post a new thread!
In the mean time, want to change the pads on my 54 plate V50. Anything unusual or are they similar to other cars? Any advice really appreciated

The chrome strip to the door protector on my Skoda Superb came away after being bumped in a car park. It seemed only to be held on by tacky adhesive which was no longer tacky!

I have refixed it using Sellotape Sticky Fixers - what do you think of its chances of survival through a car wash?

I suppose it depends if there are any gaps between the trim and the door, for water to gain access and/or the fixers are up to the job, lol.

Maybe double sided carpet tape, would work, if the door area and the trim were cleaned with isopropyl or similar.

Are the Sticky Fixers individual or is it a continuous strip? I ask because if it's individual Fixers then there is also a VERY good chance that water will remain behind and cause rust.

Thanks Gem - no problem likely with rust. The main door buffer is a wedge of heavy duty bumper like plastic. Set on this plastic is a strip of adhesive that is no longer sticky enough to hold on a stainless steel trim.

Wondering if the reason for this method of fixing is to give flexibility for expansion of metal against plastic.

The plastic bumper appears firmly fixed to the door and may require dismantling of the door linings to release. In any case a replacement bumper including the stainless steel trim looks rather expensive!!!!

As I intend to run the car into the ground I will be quite happy driving it without the stainless steel trim should this be necessary.

Your local Motorworld (or similar shop) should sell the proper double sided trim fixing tape. You thoroughly clean and dry the area where the trim fits, and thoroughly clean and dry the back of the trim. Get the hair dryer out. Warm up the area and the trim. Quickly stick the double sided tape to the trim, peel off the protective layer, and push the trim exactly into place. Play the hair dryer over the area to get it quite hot to the touch (but not hot enough to melt the tape or plastic), leave to cool, and you have a permanent job

I refitted all the plastic and chrome trim like that to my Peugeot seven years ago after a full respray, and that car is still running round with all its trim intact, despite the fact that the current owner has taken it through a mechanical car wash twice a week for the five years he has owned it

Hi all,I have a Capri Laser with a 2.0ltr Granada (circa 1985 ish),its got a breathing problem in that it sucks in air through the oil filler-cap.

I have replaced the oil-pump,hoses,breather-valve(what sticks out on the side of the block).Aside from now having a much improved oil pressure,the breathing problem remains,albeit perhaps a marginal improvement.
As a result the engine is also constantly going out of tune,to the extent of a lot of "overrun".
Im at a loss,so is the mechanic.......

Any ideas most appreciated

Have you checked to see that you're not in fact getting things clogged up by very oily fumes there, as it's common for the piping to get this way ?

The worst one normally is that from the engine block breather into the airbox or air intake trunking, and would probably be about 25mm or so in diameter. Sometimes they collapse internally as the piping delaminates or get clogged with burnt oil. Other smaller breathers can also get affected similarly if part of this network.

Blow through them to see if they're blocked.

A Haynes manual should explain how to do this.

Failing that, a close examination of the area should show how the bracket is fixed.

Angry Re: Car mechanics forum - help!

I just did parked my 2000 Volkswagen Jetta diesel and in five minutes attempted start engine again - not even little click sound came out. Battery is fine. What other problem than faulty battery there can be ? Maybe starter gone? Is there other electrical relay involved in starting procedure?
Please give me hint what to do - thanks. Karel

It might be that the starter's solenoid points have carboned over.
Sometimes it's possible to give the starter motor a sharp rap with something like a light hammer or wood block, just enough to jar any loose stuff off the contacts.

Are you sure the battery really is fine ? It should show around 12.4V without load and about 10.5V under starter load.

The first thing to do, as the battery appears to be fine, is to check the battery connections are secure. If one of them is not fully tightened, then you can end up with the exact problem you are experiencing.
Oxidisation between the battery clamps and battery terminals can also cause this. Loosen the positive terminal, wiggle it about, and tighten it again. Repeat for the negative terminal. Now see if things have improved.

On a 1993 BMW? What model BMW is that? I don't know about BMWs made since 2000, but I've never heard of any BMW from before the year 2000 that did anywhere near 44 mpg.

Hi
it was a bmw 320i estate theres still a few number of them about g reg is 1993 old have not seen an old classic bmw like the 635
Yes this water 4 gas the way it works is not by direct injection into the cylinder like say suburu STI's.
what i am doing is using water to save petrol you use a glass jar and inside the jar is 2 coils of stainless steel wire and a plastic holder for the wire to wrap around then the top the jar is covered with a lid which has 2 pipes that come out of it they go to the airfilter housing and the other pipe will go to inlet manifold. Then in the jar is distilled water and in the water you put half a tea spoon of baking soda then the 2 wires that are in the water are connected to the battery via the ignition live and the other to an earth when the current goes into the wires a chemical reaction happens and it starts to bubble it forms a gas and that gas is called HHO hydrogen and oxygen it burns beatifully and provides loads of energy and uses little water

if that dont work try this
if you can find the starter motor it has wires on it see if they are connected to it because they can come loose then if thats ok give the starter a little wack with hammer it might just be sticking.
ok cool.

Hi
it was a bmw 320i estate
Details below found on the internet from several sources.

Automatic transmission, manufacturer figures 27 mpg
Manual transmission, manufacturer figures 31 mpg

These figures are for the saloon. The estate does a little less to the gallon due to the extra weight.

That is a lot short of the 44 mpg you claimed, especially considering the manufacturers figures are based on the car on a rolling road with no passengers, no driver, no hills, no wind resistance, and an empty fuel tank, with a single gallon of petrol hanging on a bracket with a pipe to feed the engine, and a constant top gear speed of 56 mph.

As soon as you put it on the road with fuel in the tank and a driver behind the wheel, you've lost some of the official mpg. So there is no way in the world it can do 44 mpg, and no modification is going to bump it up to 55 mpg.
