what did you and your mk3 leon do today

[tracktoy]

Still on the hunt for cause of my poor mpg.

Swapped out the Map sensor for a new one and plan to change the upstream o2 sensor, see if it makes any difference.

Probably not but worth a go as I have no other idea why it’s so bad

Sorry If I have missed it but have you run a scan on the car to see if its telling you about any issues.

Yeah scanned with OBD11 no faults to indicate any issues. And because of this Seat won’t investigate or look any further into this. So let with me to see if I can figure the cause once and for all.

At this point feel like I’m just throwing money at it, by changing the sensors. Hoping they’re going bad and not throwing a code.

Brakes don’t seem to sticking judging purely of wheel temp after a drive.

Although have noticed a squeeling like nose when accelerating - Unsure if this is coming from the brakes or elsewhere on the car…Currently looking into this

fuel consumption been a long term issue since ive had the car never been impressed - averaging 30mpg even on long runs best I’ll usually get is 35 if I’m lucky.
Saw 40mpg once or twice.

Have spoke to people in Cupras getting the same if not better long term MPG. And those in the same car with the same engine averaging 45+ easily.

I have no idea why it’s happening but it’s genuinely made me dislike the car, wish I just got rid of it shortly after I bought it.

Honestly think ive just a lemon.

Have noticed the car seems to vibrate a bit more as of late at idle, however I don’t know if it’s just me looking for an issue that’s not there and be overly sensitive.

But don’t want to derail this thread with my mpg woes.

Only other thing I can think of having a look at is the Throttle Body and see if it’s caked in dirt.

I think the in the new year going to see if I can just leave it at Seat for a week and ask them to drive it and see what they experience. As definitely something needs looking into beyond just if theres any fault codes

Drove it to a BMW dealership and purchased a 128ti. Now need to strip out the MIB2 unit before I Cazoo the car. 6 years, but time to go petrol. My commute is too small these days and the diesel just isn't getting warm.

Been a great car and will miss aspects of it, but looking forward to new instead of nearly 10 years old.

After several weekends of either rain or decorating I’ve finally had the chance to clean the car I doubt it’ll stay like this for long

2016 1.4 ecotsi

Changed spark plugs (took longer than expected due to needing a deeper socket) and did an oil and air filter change.

Sold it, well hope I have. Used motorway so just need them to collect. Oh and I need to clean it and remove the stereo, pedal covers and foot rest

Squeal under acceleration sounds like a loose boost hose or connection in the boost pipework somewhere, possibly not enough to throw a code.

100% this ^^^^^^

Gonna be working in the engine bay this summer so I invested in some hood struts.

Changed my FR badge.

Thanks I have the seat extended warranty

Will book it in for the new year and see if can get it resolved.

On another note
Fitted new oxygen sensor now.
Still no closer to bad fuel consumption issue sadly

the site looks to be down at the moment.

This looks like it's only €50 now?

Replaced original rubber valve stems with black metal ones.
And plastic caps with bright silver metal ones from genuine SEAT Accessories, they are quite nice.

Yup and they lasted about 5 minutes. I've had them in the boot since. They popped out when opening the door especially as you're not used to them being there and have to adjust the way you open and close the car

If you're near Basingstoke, I'd give you mine to try as my car should be going next week

One thing to be aware of with metal caps and stems is that they can seize, not sure if a silicon lub on the threads can prevent it happening.

If you check your tyre pressures regularly then just a drop of oil now and again will keep them ok.
I had metal caps on my bmw for years and every 6 months or so a drop of oil kept them fine.
