UPDATE: Drilled a hole in the underside of the Throttle Body (This was quite simple..... used a metal drill bit in a normal battery drill) Tapped out the securing pin and cap Unscrewed the two torx screws for the metal circle Remove the metal disk This will allow the centre shaft to be removed NOW WE KNOW THE ISSUE: So the issue is a BROKEN SPRING! ...... so the next questions ........... can I get a replacement spring and how much is it going to cost

So..... I've found a video on Youtube Next step is to remove the throttle plate (Metal circular thing) by removing the 2 x Torx screws ........ then comes the weird bit You have to drill the throttle body from underneath with a 2mm drill bit ...... once drilled you can tap out the holding pin ........ then the central shaft will slide out See images:- Top - circled green (where the pin is) - Bottom - circled run and arrowed (Where to drill) Once the shaft is out this will give access to the spring Guessing further posts to come

Hi Forum ...... i'm back The 2nd hand Throttle Body is doing well in Mum's Fabia! I've started taking the other one apart ..... and would like to know how I do it fully I've took off the metal clips Removed the end plate Removed the free gear Now I'm stuck ..... what do I need to do get the black plastic gear off? I think the fault with the Throttle Body is a broken spring as the gears look in great condition If I can fix it it can either be sold to a forum member who may need a cheap repair or can be used for a spare for Mum's Fabia

Finally: I am now in the possession of a broken throttle body ...... I'm going to open it up and see if it can be repaired. If it needs replacement gears or springs if anyone has a URL for a service kit could they ping it below Finally Finally: Thank you to the forum for keeping me and my brother sane with good advice ....... greatly appreciated 😁👍

UPDATE We managed tp source a second hand Throttle Body from Charles Trents (https://www.trents.co.uk/) - Had to give it a bit of a clean but didn't have to scrub the life out of it and bathe it in acid It was ordered on Tuesday - Delivered Wednesday and it was fitted this evening (Thursday) Luckily we found out that my brothers other mate works as an apprentice mechanic at a VAG specialist garage and he managed to borrow the garage laptop with VCDS on it He replaced the Throttle Body and did the necessary with VCDS Brother took it for a 10 mile test drive and it seems to be behaving........ it's now over to the person without any engineering sensitivity (Mum) to put it through it's paces At the moment Mum isn't happy as she thinks it's a bit of a bodge whereas my brother and I think it's a bit of a result and replacing OEM Part for OEM Part (exactly) made sense ....... especially when both parts have 12 Months Warranty If we have an issue with the new second hand one we can source a new new one from Autodoc ...... Same Magnetti Marelli one for £281 (Inc VAT Delivered https://www.autodoc.co.uk/magneti-marelli/12827481) We would have done this but they're out of stock and we thought we'd take a punt and try and get Mum Mobile again (so she can visit mates and go to Keep Fit Classes) Costs: So instead of: - £420+Vat for Genuine New Throttle Body + £85+Vat (for fitting) total approx £600) It's been £108 (Delivered) for Genuine 2nd Hand Throttle Body + Beer Money (for fitting) total approx £150 Other costs: £70+VAT for the non beneficial auto-electrician diagnosis Question Do you think we've done the right thing with a second-hand part? - What would you have done?

UPDATE: We had a visit from my brothers mate who was going to take the throttle body off and give it a clean...... however, it was spotless He then plugged in his OBD2 reader (his was £1500 - the auto electricians was £4000) - We turned the key on the ignition and got a "crunching" noise from the Throttle Body The throttle pedal was pressed and there was a small movement in the butterfly valve and a bit more "crunching" More importantly, he was reading voltages and % throttle values from the accelerator pedal So, it looks like those little plastic gears in the throttle body are f4ck3d (broken) We're now resigned to purchasing and replacing the throttle body VAG's network operates in a clandestine way when trying to get part numbers and prices ....... and we're not very trusting of aftermarket parts ...... so it looks like around £500 for a throttle body and £100 to fit On the upside once the TB is replaced I'll have a broken one to play with and I might be able to find a service kit somewhere and fix it It's disappointing that a TB has failed on a 6 year old car that has done 36,000 miles and has been serviced annually But we all know ..... it is what it is! PS Sensors may be this cars achilles heal as it had the Turbo actuator replaced under warranty in Feb '21 PPS Thanks to all for the supportive feedback ....... you've been great!

UPDATE: A bit extra ....... my brother picked the car up from the auto electricians and apparently the P0638 has turned into two new numbers P029900 - P155800 So we're now slightly more confused than we were before ....... and they quoted £630 to replace the Throttle Body

Update: This is for my benefit ...... so I can track my story Diagnosis: Have been let down by the Auto Electrician who didn't have the full tools to diagnose the issue properly. Was expecting them to say voltages look OK on the accelarator , throttle position sensor etc My brother just got ... Error code says Throttle Body and it feels a bit sticky Feel slightly ripped off for the £70+VAT Could have bought my own OBD2 reader to tell me that Battery: The Exide Battery on the Fabia was a 59AH - 660CCA which was replaced by a Varta 60AH - 640CCA so was very close on spec Next: I'm going to take a look and if I think I can give the Throttle Body a clean (without breaking clips / damaging wires etc) I'm good to give it a go If that doesn't do anything will ask the forum for some advice on who to contact that can diagnose the fault properly Obviously ..... if it is a knackered Throttle Body it's a knackered Throttle Body and needs replacing ..... however if the Throttle Body is replaced and it isn't it will feel like a kick in the nether regions Replacement Cost: Also trying to get consistent prices for OEM and after market replacements is ridiculous - we've had prices from £180+VAT up to £770+ VAT Then we'd probably need to get it fitted and coding done as I can't see myself doing that Registration: FL18 AOP Engine Code: CHZC794713 References off the existing TB: A66 Magnetti Marelli VW 353.1 06.26.20 00 04C133062C

UPDATE: We're going to get the battery fitted tomorrow and we've got a slot at an Auto Electrician on Thursday They're going to do some proper scans and hopefully narrow down what the fault could be (and they'll code the battery) They've been recommended by another Auto Electrician and apparently, they have the correct kit General Info - Throttle Body - OEM Part No: 04C133062C Parkway VW wanted £504 for the Magnetti OEM Part GSF wanted £370 for the same OEM part A trusted local motor factors quoted £590 for OEM and £219 for aftermarket All prices Inc VAT

Thanks again to all who have contributed to the quest

Microsoft Co-Pilot advises this: Do the people agree with the AI?

Another fantastic reply! ......... and exposes how little I know about how cars have evolved (I drive an '08 Auris and my brother a '10 i30) This is where I show my naivety and ask for a link: Can someone provide a link (or steps) to how a battery is coded to a vehicle ..... appreciate this is going to be complex ..... as it's probably a combo of ..... get this software / get this cable / go to this area / enter this value (type of thing) Green Flag Callout - Battery - Was advised that voltage looked a bit lower than "normal" and 5 cells weren't as strong as they should be Scanner - This was a picture taken by my brother at the time of the callout - Codes were cleared - Car was rescanned

Fantastic reply! 😁👍 Yep..... appreciate it could be electrical but you try and explain that to a pensioner parent who has no mechanical sympathy and is threatening to drive the car in Limp Mode!! I did check the battery connections and all were tight - I disconnected the battery for 15 minutes but nothing reset when re-connecting - We have ordered a new battery as the existing one is 6 years old anyway (Ordered a decent Varta one 640CCA - 4 Year Guarantee from Tayna - being delivered tomorrow) Will continue on my diagnostic path Any pointers are appreciated...... by me, if not by Mum!

Hi Forum Mum has a 2018 Fabia that has gone into limp mode - Also the Start-Stop is complaining of an Error She managed to get home and we called Green Flag who plugged in a code reader Code returned P0638 Q. Is this a throttle body sensor error or a throttle body error The throttle body is a Magnetti Marelli VW - 04C133062C Q. Do you repair or replace Q. If replaced, what is the difference between them as the costs can vary and some say they require learning / teaching of the throttle body Final Question Q. Can someone provide a few suggestions of where to obtain a throttle body
