Exhaust issue

[brummiered]

Exhaust light showing orange what do I need to do phoned skoda they said £125 per hour diagnostic 

[varooom]

Check your car manual, it will most likely be DPF clogged up.

 

Please also respond with mileage of the car, every little information helps.

 

 

You could also find someone on the map to bypass expensive dealer visit and get a VCDS scan for some beer tokens.

Mileage 99041 what is dfp

Thanks for help

If your profile is correct, and this is a 1.6 Petrol Octavia, then it can't be a DPF issue. DPF is diesel particle filter, so you don't have one.

 

Exhaust light could come on for a variety of faults, only way to know is to scan it and read the fault code.

 

If you can't find a local member with VCDS, most independent garages should have the equipment to read fault codes, much much cheaper than main Skoda dealer prices.

DPF is Diesel Particulate Filter.  So if you are petrol, it won't apply.

@brummiered  If that was a Skoda Dealership you phoned then at Participating Dealerships in the Fixed Price Servicing & Maintenance the first 30 minutes of a diagnostic is £60.

For a reason best known to Service Desk staff that never seems to get mentioned to callers.

Maybe because they know their tech will be more the 30 minutes with reading fault codes and checking things. 

 

?

Is your car a 1.6 FSI so petrol or a diesel?

 

EDIT.

Best plan seeing if a Briskoda member can help with the diagnosis..

  If it is not simply fixed and within your ability then you want a good independent mechanic or garage anyway and not a main dealership.

toot ... any thoughts on the mechanics diy 10mm hole in the base of the dpf ? .. watched it being done and told the reasoning 

[J.R.]

Care to share it with us?

 

You cannot ask for thoughts on something that has not been explained.

Change your garage. As others, a petrol car cannot have a diesel filter in the exhaust.

[promomast]

yes ... on a train at present 

 

id like 'toot' thoughts on this

 

it is of course outside the bounds of 'ethics' let say

yus but i have a diesel ... and petrol cars can't drill into that which doesn't exist 🙂

[Ootohere]

@promomast  I know nothing about diesels even though i have one.  Pre DPF.

 

Plenty here do know their stuff.

 

?

What was the reason for drilling the hole, did they think that was resolve s blocked DPF or something?

[promomast]

hi toot ... it tricks the system into not limping the engine if too much soot i'm told by a very reputable honest sort of mechanic ... doing it to his own audi on the ramp 

[Ootohere]

I look forward to the opinions and knowledge from others here who work on them. 

like @ApertureS

 

Anything can be worth a try when desperate, what is the worst that can happen!

My feels are,,,

[Ootohere]

Advisory on my diesel at this years MOT.   Sounds quite good for a 3.2 DI-D.

Nobody with even half an understanding of how a DPF works would suggest doing that

They may not have a diesel particulate filter but new petrols do have a GPF gasoline particulate filter.

mmmm genius idea… not! You drill a hole pre dpf to keep the pressure sensor from triggering. The gases will always take the path of least resistance which with a partially blocked dpf and a open hole, the gas is gonna pour out the hole, you’re gonna get soot everywhere, cancerous gases straight through your pollen filter into the cabin, possible chuffing sound.

 

ask anyone that’s ever driven a diesel with a exhaust leak - if it’s bad enough you’ll have your eyes watering and coughing, and yet you want to do this on purpose????

 

Next you’ll be saying if you’ve got a seized brake caliper just crimp the hose off and remove the caliper completely…. 
 

just fix the issue properly!

This is not even mentioning the fact that -

It’s an mot fail

It’s now illegal

its near impossible to hide on an mot cause of the noise and soot build up

You run the risk of the excess oxygen now in the exhaust causing a fire when the regen cycle starts

the EGR won’t operate correctly 

[Ootohere]

@ApertureS I was not being serious about the noise.  

189 miles between MOT's and the leak is dealt with.

Found problem but 

Where do I find exhaust sensors on exhaust 

[Guest]

They will be the bits with electrical wires connected to them!

There are many sensors

 

which one? Lambda, pressure, temperature, nox?

 

Also - just because a sensor is showing faulty doesn’t mean it’s faulty. For example - dpf pressure sensor showing open or short circuit 99% of the time means neither and is the voltage reaching above or below 0.5-4.5v due to extremely high or low exhaust pressures.

[brummiered]

Lamdra I think 

Found one that top of exhaust can't find the other

[brummiered]

how do i get clip off lambras
