So I'm close to collecting a 2006 Mk2 Octavia 1.9 tdi 4x4 Octavia. I currently drive a Mk1 Octavia 1.8t L&K estate and have previously had a 1.8t 4x4 hatch, both of which have been bulletproof. The 4x4 followed and passed Land Rovers up and down snowy tracks for months on end as well as one outing on a motocross track    with no issues. It had done 108k miles when I was done with it.

 

Is the Haldex system in the Mk2 pre-FL just as good if not better for reliability? The one I'm looking at has 109k and according to the service history has only had 2 Haldex oil changes which is probably more than most have but still not ideal. As far as I'm aware my Mk1 4x4 never had one. Other than general wear and tear is there anything I can expect to go wrong around this mileage?

 

I also notice it's a 6 speed rather than 5 speed like the non 4x4 1.9s, is this good or bad for reliability?

 

I'm completely glossing over the engine because I don't see anything going wrong with a well maintained 1.9 PD105 at 109k miles but please let me know if this is wrong. I'll probably be getting the timing belt done soon after purchase.

 

It will also be getting mapped as soon as I've given it a proper shakedown whilst still under dealer warranty...  I'm assuming there is no risk to the Haldex with a bit more torque?

 

Thanks
Toby

Had mine for 3 years now, also had it remapped about 2 1/2 years ago. Been 100% reliable, mine only on 60k now though. Fuel consumption improved by 5mpg after the remap, and completely transforms the car.

Search on here for Haldex pump, there have been a few issues of corrosion on older cars which allows moisture into the electronics.

 

Also get well under the car and check the Haldex and diff for oil seepage - a sign of weak or failing seals.

 

My local main dealer charges £60 inc. VAT for a Haldex oil change - well worth it every 40K in my opinion. I'm sure it could be negotiated for even less if you have it done at the same time as the cambelt.

 

Has the car got a towbar or signs of one being fitted? The 1.9 TDi PD105 is as you say bullet proof if well maintained but the 6th speed on the gearbox may give issues if it has been towing for a lot of those 100K+ miles in 6th.

ive had both a mk1 1.8t 4x4 and a mk2 105 pd 4x4 both were bulit proof for me the mk2 is a far supierior car you will get auto wipers,jumbo box arm rest,and duel zone climate as standard plus 45+ mpg with the diesel 

 

the only thing i would be cautious of is the duel mass fly wheel give it a good road test and check how it bites when on a slope when warm

 

haldex oil should be changed every 40k

 

the mk2 has the better 2nd generation haldex system the same as the mk5 r32  your mk1 4x4 will have the 1st generation haldex like the mk4 r32 golf ,i personaly didnt notice much difference between the haldex systems if any at all my mk1 was 200bhp and always gave very good grip .   

Probably worth changing the Haldex filter as well as the oil. Skoda say it doesn't need replacing but after a 100k it can't have been good anymore.

All replies appreciated, car I was after has sold but one has popped up with less miles, better history and £1200 cheaper so all good at the end of the day!

 

Have seen a couple of instances of rod failure in the PD105, is this something that should bother me as someone who maintains my cars properly? Is it seemingly random or down to lack of maintenance causing main bearing seizure?

 

Yes the car I am now looking at has a towbar fitted and will be getting used by me as well to tow a camping trailer and to hang bikes off. I'll be extra vigilant on the lookout for gearbox noises thanks. Some things I've read suggest I might want to switch gearboxes anyway for something a bit longer geared.

I thought it's just first gear which is lower than the Fwd cars.

Pretty sure it's just 1st gear that is different. Pull off and you have to go into 2nd really quickly (perfect for towing), but after that it's pretty much the same as other octavia's. It's a lovely and smooth gearbox, at least it should be, so any baulking or noises, just walk away. The 1.9 tdi 105 is a cracking engine, especially when remapped, loads of midrange shove. I've said on here before that i really wanted a scout, but wasn't prepared to pay the substantial hike, for what is essentially a bodykit and wheels. The amount of issues that seem to pop up with dpf's mean i'm glad i went for the 4x4 as it doesn't have one. Another bonus in the reliability stakes.

Again, all good cheers.

One of the first things I think I'll be doing is scout suspension if possible as I'd appreciate the extra ground clearance.

Scout suspension is the same as the 4x4, they have slightly higher ground clearance due to bigger alloy wheels and tyres but exactly the same otherwise.

That partially confirms what I'd been thinking based on the 225/50r17s fitted to the Scout. I shouldn't have any trouble fitting the 205/70r15 all terrains I would like to fit then.

 

Thanks again. Briskoda is proving very useful already.
