Hi all,
Hoping you can assist me with nuggets of information that may help get to the bottom of some Altea running annoyances please?
Firstly, I have a rather annoying rough idle from cold, in that when you first start the car it's okay for 60 seconds. However as soon as the car gradually warms to the normal operating temp it's lumpy as hell, and is what I would class as a 'pulsing' idle (if that makes sense.) If you slowly depress the throttle to just over 1k revs (slowly moving) whilst this pulsing is occuring, the car 'kangaroos' in the same motion. Once the car has warmed, the issue goes away.!?
Now searching the forum, there has been similar descriptions with white smoke etc. but I don't get any of this.
I have recently ran some Wynn's Diesel power 3 through and had a normal service with no change. Before I purchased the car in October '14 the owner had changed the cambelt, so was wondering if it may be a timing issue (but wondered why just at cold idle)?
The second issue is really poor MPG, currently I can only get around 400 - 450 miles to a tank, which to me is poor (nothing really to compare it against). The onboard computer is showing 55MPG but I think I worked it out to be more around 38 to 40 MPG in real world terms.
I'm not sure if this is related, or if there is something 'common' that may cause this, but does seem a bit low. My driving is what I class as normal (never over 80 on Motorway) 70/30 split on Motororway/A roads.
A recent MOT pointed out a slight sticking rear caliper, not sure if this would be enough to generate the loss in MPG (I would think not) - but will get it sorted regardless.
Open to any ideas or suggestions if you can, would be really appreciated![[B)]](/forums/styles/seatcupra/oldforumsmileys/shades.gif "Cool [B)]")
I'd rather try a few fixes from knowledgeable SEAT owners than just chuck money at it in the hope something resolves it.
