CONTROL SYSTEM FOR EXHAUST GASES warning light

Followers

28 December, 20214 yr

Have just aquired a 2005 Octavia. Topped up at Sainsburys for a trip to Gloucester from Taunton and had the Control System for Exhaust Gases light come on. Checked the manual and this forum and it seems that quite often this light reflects (sic!) a minor and often transient error even just connected with choosing either 97RON or 99RO fuel. Anyway there were no unusual noises from the engine and no change in performance so did the trip on the basis that it might even be a sensor error. However, it seems prudent to purchase a diagnostic tool and they can range from £10 to close to £100, or more. I have been recommended a MaxiScan MS509 KW808 OBD2 EOBD which shows at £48.99 on eBay. What does anyone else recommend please which might be of equivalent quality bearing in mind that quite often the same platform and software is used in different products and sometimes with widely differing prices.

Thanks in advance for any helpful comments or suggestions.

ODB port not connecting to scanner

ODB port not connecting to scanner

cjmason88 · 27 October, 202527 Oct

I have a 2010 Fabia 1.2 and the ODB port isn't playing ball. Tried 2 different scanners and they both fail to auth with the ECU. I initially thought it might be a bad fuse so I replaced num 22, didnt change a thing. Slipped the port out of the dash and made sure that the wires are fully seated in the connector, no change. I've tried with electrics on and also engine on, doesn't make a difference. Does anybody have any suggestions on what to look for next?

DIY ABS warning Fix

Lambo1 · 21 minutes ago21 min

Yesterday our Roomster started beeping and flashing the warning light about the ABS. My first thought was to replace the ABS sensors – they are around £7 each and seem to be easy enough to replace by removing the rear wheels. I could also give the connections a bit of a clean at the same time. What are my chances chances of fixing the issue within 45 minutes of DIY work? I don’t have any diagnostic tools, but if this is a common fault with an easy fix it would be great to know what other peo

Motecarlo, 1.2TSI 105hp 2014 Timing chain tensioner failed

AF185 · 20 hours ago20 hr

Hi, My tensioner failed at low revs and speed, the car juddered and stalled. It restarted and I drove home about a mile steadily. It seemed to drive normally if a little noisy. Next day it would start but not run. The check engine light was on. Pretty sure the Timing jumped a tooth. Q. do the valves always hit the pistons? do the valves always bend? Might I get away with an new tensioner and re-time? TIA

Does the Skoda Superb EA888 Gen 3 (CHHB) use dual injection or only direct injection?

Does the Skoda Superb EA888 Gen 3 (CHHB) use dual injection or only direct injection?

username8888 · yesterday at 10:051 day

Hi, I'm looking at a 72k mile Skoda Superb 65 plate, hopefully lots of motorway miles. It looks good, my main concerns being the lack of dsg oil change & potential for carbon build up due to direct injection. I currently have a mk6 Golf GTI (EA888 Gen 1) which didn't support dual injection & bit me when the carbon build up & clogged injectors caused a flooded cylinder. I've tried to research this but I'm getting conflicting information around this engine & I wasn't sure if s
