Annoying limp mode error codes 19461-17946-17957

Hi all

I am running a mk 1 Octavia 1.9 tdi that keeps slipping in and out of limp mode. Error codes 19461-17957-17946 are repeated every time the diagnostics are plugged in. I have replaced the fuel cut off solenoid to no avail. My motor has now started to make a loud buzzing sound immediately after I turn off the ignition that lasts for approximately 20 seconds. On a previous thread I read mention of a dodgy relay associated with these fault codes. Can anyone shed light on my plight?

Boost pressure fault
Skoda Superb Mk3 (2015 - 2023)

Boost pressure fault

seanw · just now1 min

Howdy folks. Late 2015 model 150bhp 2.0tdi no ad blue. If I push on over 3k rpm the car feels like its running out of steam. If I keep pushing it will go into limp mode and throw the fault p0299 (boost pressure regulation range not reached) Ever since I got the car 6 months ago it is very smokey on hard acceleration taking off etc. I have a feeling the dpf has been removed/mapped out before I got it. It has high mileage. Drives pretty normal the rest of the time. Decent acceleration under norma

Which OBD is best? 1.6 diesel

Hi again. The service light won't reset using the press the trip method ,also the aircon won't blow out of the face vents despite recalibrating (might be another fault I guess) so Im thinking I'll need to reset the service light with a diagnostic tool Which one though? I should add I've never used one .

DPF worries

jtj321 · 22 hours ago22 hr

Hi again. I have a 1.6 tdi My daughter recently had to sell her VW Sharan after the DPF was pronounced dead. At least 2K to fix,probably much more.Her car was low mileage,full service history. Can I protect the DPF on our much older vehicle,are there options if it clogs up? Thankyou

EGR error after replacement
Skoda Fabia Mk1 (1999-2007)

EGR error after replacement

Erdmi · 20 hours ago20 hr

Hi everyone, I have a Skoda Fabia with a 1.2 AZQ engine. I have a warm running issue - the car misfires/stutters when fully warm. The intake air temperature (IAT) reads around 80°C when the problem occurs. When I unplug the EGR connector the car runs perfectly and IAT drops to around 30°C. Parts already replaced: EGR valve (new) + adaptation done MAP sensor (new) Coolant temperature sensor (new) PCV valve (new) EGR pipe is clean, no carbon buildup Breather hose between EGR and air filter ho

1.4 tdi greenline boost leak
Skoda Fabia Mk2 (2007-2014)

1.4 tdi greenline boost leak

Skezza · 27 May, 20242 yr

I'm off the back of a long ish drive and about 5 mins before I arrived, the car developed a boost leak (I think). Before anyone says search, I've done searching, plenty of it. Not really found anything specific to the greenline though and what I can potentially do. The car feels underpowered (more so than usual). It whooshes in lower gears as the turbo spins (loudly if I need to get up a hill) and cuts instantly out when I change up or dump the clutch. I've checked the larger top ho
